Although differently sized busts cause no difficulties physically, many women suffer because of how they look. When women wear bras with too big a band, breast support is reduced.
All you need to do is take measurements of your bust and underbust sizes in inches or in centimeters. You need to use a measuring tape to get accurate measurements of your bust and your underbust. It is also advisable to note your size in centimeters. Then, all you need to do is to refer to the generic size charts found below. It must be noted, however, that exact measurement of each bra size may vary depending on the brand or manufacturer.

To accurately determine your bra size, you need to take measurements of your band size and your cup size using a measuring tape. You may seek the assistance of a professional or a trusted friend to accomplish this. You may also choose to take your own measurements, but it is best to do this while standing upright in front of a mirror. Keep in mind that you should not wear a bra or loose clothing while taking these measurements.
Also known as your underbust width, you can measure your band size by wrapping the measuring tape directly under your breasts. Make sure you are breathing normally when doing so and that your chest is relaxed. This prevents the likelihood that you end up taking your measurements incorrectly. Write down the value on a piece of paper in inches and in centimeters.
In principle, you should measure under the bustline twice. The measuring tape should apply loosely around your upper body. It is important that it does not pinch the skin. In addition, you should let yourself inhale during measurements. You then enter the determined length. Then you should apply the tape tighter around your upper body for a second time, this time allowing the tape to pinch the skin slightly. This time you should breathe while taking measurements and enter the value.
Before you can get your cup size, you need to measure your bust size. To do this, you need to wrap the measuring tape around your upper torso and on top of the highest point of your breasts i. Make sure that the measuring tape is at the same height in the back as in the front and that it is parallel to the ground. Take note of the measurement in inches and centimeters and write it on a piece of paper. Now look up your bra size in the bra size chart above or use the bra size calculator.
Cup sizes typically vary per country, especially for larger bra sizes. Make sure that the measurements you are subtracting are in the same units; they must be both in inches or centimeters. Once you have the difference, all you need to do is refer to a size chart to determine the alphabetical equivalent of your cup size.
A sample chart for U. If you plan on using a bra size calculator like the one provided below , you may not even need to calculate your cup size.
All you may have to measure are your underbust width and your bust size, and once you have inputted the appropriate information to the calculator, you will then be provided with the bra sizes which suit you best.
Shopping brassieres can sometimes get frustrating. And even if they do have your size, something may be slightly off with the fit. For example, maybe the cup size is just right but the band size is too loose. Some women may immediately take this as a sign to move on and search for some other bra that might fit them. In determining your sister size, you have the option to go one size up or one size down. In doing so, the number of your band size and the letter of your cup size shifts by one size.
For example, if your bra size is 34C, you have the option to try either a size 32D or a size 36B. You may refer to the chart below and use it as a guide to help you identify your appropriate sister sizes. The adjacent sizes to the left one size down and right one size up of your real bra size are your sister sizes. A bra, which is a shorter term for a brassiere, is an undergarment that is meant to cover the breasts and provide support to the person wearing it.
It is regarded to be among the most complex garments to ever be manufactured. Its main components include:. Bras come in different shapes and types, which serve various purposes and are meant for specific body types.
As a guide, here are several of the most common bra styles currently being sold in the market:. At present, the clothing industry has made it possible for women to choose their preferred brassieres from a wide selection of styles which suit their needs and tastes alike.
Choosing the perfect bra, however, is more than just about fashion. Believe it or not, wearing an ill-fitting bra can actually make you sick. It can cause headaches and neck pains, which may eventually lead to posture problems.
Even worse, it might negatively affect how well your lymphatic system functions. A lot of women, as it turns out, do not wear the right bra size.
This is because many of them do not take the time to consult with a professional regarding their bra size or even take their own measurements. Instead, these women rely on the size of their old and used bras when shopping for new ones. This is supported by our study participated by 1, women who were asked in an online panel about bra sizes.
Result of the survey showed the following:. Ever wonder why you have the set of breasts that you do? Here are four of several factors that influence the size and shape of your breasts:.
There are several red flags to watch out for when fitting bras, and once you encounter one, you need to either size up or size down. Here are some of the signs that you are wearing the wrong bra size:. To find a great-fitting bra that provides optimum support and gives you a more flattering form, it is not enough to take your underbust and chest measurements as well as your cup size in consideration.
You must also think about the shape and positioning of your breasts. Here are several breast types and the bra styles that suit each one best:. Do you have a slightly larger bust?
Then it is important that your bra is the right size and fits well. As a rule, a big bust is very heavy and should be properly supported with the appropriate bra. Women with a large bust whose bras do not fit properly can suffer from various physical discomforts. When buying, you should consider that the intended support of the bra is 80 percent dependent on the underbust brace and not on the wearer of the bra, as is often mistakenly suspected. If the brace of your bra fits too loosely and slides upwards, the bust load is transferred to the bra straps.
As a result, the bra straps intersect causing tension and pain in the back and neck area. Do you have a big bust? Then you should pay attention to the following aspects when choosing the right bra:. With breasts of different sizes, the shape of the breasts is often different, the nipples sit in different positions or point in different directions and the volume can vary from side to side.
In the case of pointed breasts, however, the course between the upper part of the breast and the nipple is conspicuous and can appear almost triangular in profile. To a certain extent, bras with molded shells act as a template and shape maker shapewear. They do not allow the nipples to shine through the upholstery and clothing, creating a balanced appearance.
To increase the symmetry in case of small side differences, the beam lengths can simply be adjusted. For larger differences in volume, on the other hand, cushions and pillows are suitable. But even then it is important to choose the right bra size first. Breast malformations, operations, and hereditary predisposition can lead to a pronounced difference between breast sizes. However, removable cushions or additional cushions can be used to achieve a more symmetrical shape.
Shell bra cups or variable padded push-up bras can be used as the basis for this. Removing removable pads and cushions on the side of the larger breast is ideal and easy. On the side of the smaller breast, on the other hand, they are inserted so that support is provided in the underbust area. On the one hand, this has a relieving effect. On the other hand, the breast tissue is pushed upwards by this measure, fills the basket and promotes a symmetrical appearance.
Even medical studies have attested to the difficulty of getting a correct fit. The current popular system of determining bra size is inaccurate so often as to be useless. Add to this the many different styles of bras and the lack of standardization between brands, and one can see why finding a comfortable, well-fitting bra is more a matter of educated guesswork, trial, and error than of precise measurements.
The use of the cup sizing and band measurement systems has evolved over time and continues to change. Experts recommend that women get fitted by an experienced person  at a retailer offering the widest possible selection of bra sizes and brands. If the straps dig into the shoulder, leaving red marks or causing shoulder or neck pain, the bra band is not offering enough support.
If it digs into the flesh, causing the flesh to spill over the edges of the band, the band is too small. Similarly a band might feel too loose if the cup is too big. It is possible to test whether a bra band is too tight or too loose by reversing the bra on her torso so that the cups are at the back and then check for fit and comfort.
Generally, if the wearer must continually adjust the bra or experiences general discomfort, the bra is a poor fit and she should get a new fitting. Bra experts recommend that women, especially those whose cup sizes are D or larger, get a professional bra fitting from the lingerie department of a clothing store or a specialty lingerie store.
There is significant heterogeneity in breast shape, density, and volume. As such, current methods of bra fitting may be insufficient for this range of chest morphology. A correctly fitting bra should meet the following criteria: One method to confirm that the bra is the best fit has been nicknamed the Swoop and Scoop.
After identifying a well-fitting bra, the woman bends forward the swoop , allowing their breasts to fall into the bra, filling the cup naturally, and then fastening the bra on the outermost set of hooks. Experts suggest that women choose a bra band that fits well on the outermost hooks. A bra is one of the most complicated articles of clothing to make. A typical bra design has between 20 and 48 parts, including the band, hooks, cups, lining, and straps.
Major retailers place orders from manufacturers in batches of 10, Orders of this size require a large-scale operation to manage the cutting, sewing and packing required. Constructing a properly fitting brassiere is difficult. Adelle Kirk, formerly a manager at the global Kurt Salmon management consulting firm that specializes in the apparel and retail businesses, said that making bras is complex:.
Bras are one of the most complex pieces of apparel. There are lots of different styles, and each style has a dozen different sizes, and within that there are a lot of colors. Furthermore, there is a lot of product engineering. You've got hooks, you've got straps, there are usually two parts to every cup, and each requires a heavy amount of sewing. It is very component intensive.
Obtaining the correct size is further complicated by the fact that the size and shape of women's breasts change, if they experience menstrual cycles , during the cycle  and can experience unusual or unexpectedly rapid growth in size due to pregnancy, weight gain or loss, or medical conditions. In fact there are very few advantages in wearing existing bras. Having a bra that's generally supportive would have significant improvement particularly in terms of stopping them going south The skin is what gives the breasts their support" .
In , the most common bra size sold in the UK was 36D. Researchers ruled out increases in population weight as the explanation  and suggested it was instead likely due to more women wearing the correct, larger size.
Bra retailers recommend several methods for measuring band and cup size. These are based on two primary methods, either under the bust or over the bust, and sometimes both. Calculating the correct bra band size is complicated by a variety of factors. For the woman with a large cup size and a between band size, they may find their cup size is not available in local stores so may have to shop online where most large cup sizes are readily available on certain sites.
Others recommend rounding to the nearest whole number. A measuring tape is pulled around the torso at the inframammary fold. The tape is then pulled tight while remaining horizontal and parallel to the floor.
The measurement in inches is then rounded to the nearest even number for the band size. If the measurement is even, 4 is added to calculate the band size. If it is odd, 5 is added. Currently, many large U. A sizing chart or calculator then uses this measurement to determine the band size. A measuring tape is pulled around the torso under the armpit and above the bust. Because band sizes are most commonly manufactured in even numbers, the wearer must round to the closest even number.
Bra-wearers can calculate their cup size by finding the difference between their bust size and their band size. The measurements are made in the same units as the band size, either inches or centimetres. The cup size is calculated by subtracting the band size from the over-the-bust measurement. Cup sizes vary from one country to another. The larger the cup size, the bigger the variation. Surveys of bra sizes tend to be very dependent on the population studied and how it was obtained.
For instance, one U. However, the survey sample was drawn from Caucasian student volunteers at a Midwest U. Bra-wearers who have difficulty calculating a correct cup size may be able to find a correct fit using a method adopted by plastic surgeons. Using a flexible tape measure, position the tape at the outside of the chest, under the arm, where the breast tissue begins. Conversion of the measurement to cup size is shown in the "Measuring cup size" table. This principle means that bras of differing band size can have the same volume.
For example, the cup volume is the same for 30D, 32C, 34B, and 36A. These related bra sizes of the same cup volume are called sister sizes. A study by White and Scurr University of Portsmouth compared method that adds 4 to the band size over-the-bust method used in many United Kingdom lingerie shops with and compared that to measurements obtained using a professional method. The study measured 45 women using the traditional selection method that adds 4 to the band size over-the-bust method.
Women tried bras on until they obtained the best fit based on professional bra fitting criteria. When women wear bras with too big a band, breast support is reduced. Too small a cup size may cause skin irritation. They noted that "ill-fitting bras and insufficient breast support can lead to the development of musculoskeletal pain and inhibit women participating in physical activity.
In , researchers published research on world-wide breast size. They gathered breast data by gathering , individual breast size measurements in different countries. Only data from women in the age group 28 to 30 years. They found that women born in the United States have much bigger breasts than women in any other country.
Their average bra cup size, when converted to the European measurement system, is substantially larger than "F". The mean cup size of women of Canadian origin is "E" according to the EU bra size. Their average breast size is "D". Women born in Africa and Asia, especially those born in East Asian countries, have the smallest breast volumes. Asian women were found to have an average "A" cup size or even smaller.
Bra-labeling systems used around the world are at times misleading and confusing. Cup and band sizes vary around the world. Bra-fitting experts in the United Kingdom state that many women who buy off the rack without professional assistance wear up to two sizes too small. Manufacturer Fruit of the Loom attempted to solve the problem of finding a well-fitting bra for asymmetrical breasts by introducing Pick Your Perfect Bra, which allow women to choose a bra with two different cup sizes, although it is only available in A through D cup sizes.
There are several sizing systems in different countries. Most use the chest circumferences measurement system and lettered cup sizes, but there are some significant differences. Many bras available come in only 36 sizes. The UK uses the inch-system, this means that the difference in chest circumference between the cup sizes is always one inch, or 2.
Leading brands and manufacturers including Panache, Bestform, Gossard, Freya, Curvy Kate , Bravissimo and Fantasie, which use the British standard band sizes , and so on. However, some clothing retailers and mail order companies have their own house brands and use a custom sizing system. As a result, their J-Cup is equal to a British standard H-cup.
Their H-Cup is roughly equal to a British standard G-cup. Cup labelling methods and sizing schemes are inconsistent and there is great variability between brands. This has introduced further sizing scheme confusion that is poorly understood even by specialist retailers.
Bra-sizing in the United States is very similar to the United Kingdom. Band sizes use the same designation in inches and the cups also increase by 1-inch-steps. However, some manufacturers use conflicting sizing methods. D1, D2, D3, D4, D In , underwear maker Jockey International offered a new way to measure bra and cup size.
It introduced a system with ten cup sizes per band size that are numbered and not lettered, designated as , etc. The company developed the system over eight years, during which they scanned and measured the breasts and torsos of women.
Researchers also tracked the women's use of their bras at home. In very large cup sizes this causes smaller cups than their English counterparts. This system has been standardized in the European dress size standard EN introduced in , but was in use in many European countries before that date. They increase in steps of 2. Japanese sizes are the same as Korean ones, but the cup labels begin with "AA" for a 7. The French and Spanish system is a permutation of the Continental European sizing system.
Since it starts with size 0 for European size 60, the conversion consists of a division by 5 and then a subtraction of The size designations are often given in Roman numerals. Cup sizes have traditionally used a step size of 2. Manufacturers' marketing and advertising often appeals to fashion and image over fit, comfort, and function.
English mechanical engineer and professor John Tyrer from Loughborough University has devised a solution to problematic bra fit by re-engineering bra design Loughborough University. He started investigating the problem of bra design while on assignment from the British government after his wife returned disheartened from an unsuccessful shopping trip.
He theorised that this widespread practice of purchasing the wrong size was due to the measurement system recommended by bra manufacturers. This sizing system employs a combination of maximum chest diameter under bust and maximum bust diameter bust rather than the actual breast volume which is to be accommodated by the bra. According to Tyrer, "to get the most supportive and fitted bra it's infinitely better if you know the volume of the breast and the size of the back. It's an instrument of torture.
The average breast weighs about 0. If a cup is a hemisphere, its volume V is given by the following formula: If the cup is an hemi- ellipsoid , its volume is given by the formula: Cups give a hemi-spherical shape to breasts and underwires give shape to cups.
