Sister size

A sister size is a related bra size with the same cup volume of each other. One's sister size could, in theory, be used as a substitute for one's true size, but the bra wouldn't fit correctly.

Manufacturers cut their bras differently, so, for example, two 34B bras from two companies may not fit the same person. I decided to try Cleo and bought a 34G. The Berg Companion to Fashion.

Find your current bra size, and your sister sizes are the ones listed in the same row (going across). So, for example, if you’re a 34C, your sister sizes are 30E, 32D, 36B, and 38A: Let that sink in for a moment: an A cup can also be an E cup.
A DDD is the about the same as an F, Playtex is known to used the DD and DDD measurement for their bras. It is really best to get measured by a professional then try on bras to find the ones that fit you the best and not worry about the letters so much.

Lingerie company HerRoom's infographic points out some of the basics of bra sizing, such as measuring for cup and band size. What you might not have known about bras is that the
Bra sizes that are the same in volume are often referred to as “sister sizes”. The grey cells in the table below demonstrate how the sizes diagonally adjacent from the top right to the bottom left are the same in breast volume i.e. the same volume of breast tissue spread across different size rib cages (band sizes).

I recently bought a Fantasie bra in 38K. Do you happen to know if that would be a British or US sizing? I absolutely love your blog because I have been arguing with my mom who wears U. K 42c and she said I should buy the same size in the U. Do you think that will fit her? Unfortunately, manufacturers are not super consistent, so she may still have to tweak her size. I hope this helps, and thank you for the kind words about the blog!

That said, Bali is an American company, so you would be a 36G in it too. Even many brands, like Bali, will stop at those sizes too. If you want a slightly cheaper line that Goddess, check out Glamorise. You may not find them in a store, but they go up to US J cups. I find the quality inferior to Goddess though unfortunately. If US companies make that size, it would most likely be around a V cup. Hopefully, more manufacturers will acknowledge the need for higher cup sizes and product some options!

I bought a bra in Ireland last summer at Bramora. The lady put me in a panache 34HH and for the first time ever a bra fit!!. I have since ordered bras from Bravissimo still panache and can wear an H or HH depending on the style plunge needs to be a little bigger. If I wanted to order from a different company and try a different brand what would you suggest?

I am so tired of the guessing game and I cannot find a store within miles that I could get sized in. A Cleo by panache fits me perfectly. I wanted to know what would you recommend for strapless bra? Both give great support in GG cups! In what bra do you have the 38HH? Once I have a frame of reference for what size you need, I can better recommend which size to buy in the Lucy.

Hope that helps, and if you want to discuss this privately, please feel free to email sophisticatedpair[at]gmail[dot]com. Your blog has been very helpful!

I am afraid to go up a band size because the band seems to fit but I also am afraid the 32FF would be to big in the cup. I have tried the 32FF in Curvy Kate Emily and had to return because the straps were cutting in to my arms so I thought the cups were to large maybe???

Have you looked at other brands too? Freya and Cake both make nice nursing bras in that range! When I was a 42 bust I was wearing Wacoal in a 34H.

I decided to try Cleo and bought a 34G. At that time, if the gore was a little shorter in height , it would have fit exactly like my Wacoal I have in 34H. Same cup size , but gore came up a little higher. I still wear my Cleo , its small and I have quad but I like the firm cups. I love your blog. I love my freya.

I went to a store that is about an hr away from me. The woman had me try 2 different bras. One was a Fantasies 34HH moulded full cup the price was The other one was Elomi 36HH bandless cost was Can you please tell me what would work for me when I or a bra.

I never tried any other ones. It Fits ok in the size, but I could probably go a cup size bigger. I definitely can go up a cup. I also bought a Wacoal in a 36G, but it lefts under. So I probably would have to go at lease a size or two bigger in the cup. I only bought those because they were on clearance and my bras that I bought in freya my dog ate like 4. So I am wearing right now a 38H us that is cacique. I have a fantasie without padding and its a 34GG. I could probably go up one cup.

I just measured myself again and the bra that I have on is the white cacique 38H. The band is a little lose and the cup is a tiny big, but I wear this one when I am just laying down during the day.

It does be job. I also have another cacique that has some padding under and some Ontop. This one is a 38G and does not fit. The women told me that it would fit. I also forgot to add that I bought an Elomi about a year ago that is EL nue in a 34GG that is a hard cup or something. Yeah I tried it on at the store and the women said it looked really good on me.

So when I put it on as soon as I got home I hated it and never wore it. So once I find the right bra size. The twist I have seen on eBay for So If I sell that I will make on it. Sorry for all the post. Once I posted the first one. I forgot about bringing up the other bras. Oh and I am top havey. I had my boobs done. I had 3 kids and my girls would get bigger. I ended up getting them done again 11 months later due to one being bigger then the other one.

So the first set he put in the left and in the right when my right was always bigger. The 2nd time he put in both. I have so much breast tissue that no one knows I had them done since they look and feel real.

So hopefully I will be able to and get all new bras. You may also want to check out styles with a stretch lace like Panache Jasmine or Envy too. The lace tends to accommodate fuller tissue better, and the other styles should be open enough at the top to not cut into any tissue. Based on your measurements I would look at around the 34GG to UK H cup, particularly since you have found some bras which fit well in this size cluster, but you may want to start with H cups in general to ensure you have enough cup depth.

You may also like the following styles depending on breast shape: I hope this helps, and if you have more questions, please feel free to email me! Hi Erica nice blog! I like to look at reviews to see how people felt the band and cups ran to double-check. Do you know if that is true for her bras? Her brand is Von Follies. In addition to checking out Lingerie Addict, I would double-check Bratabase to see if they have measurements available. It does seem like there are stateside retailers of Von Follies, like Bloomingdales, too if you want to see if a local place would have it available to try in person.

The cut of the bras and the shape of the cups may be at odds with you, which can create fit issues. I ordered a swimsuit top and it was 38dd from Curvy Kates from UK which I wear in the states and it was way to small. Here are a couple sexy ones:.

I can never find bras that fit me in stores in the U. I prefer plunge bras or bras that show a little more cleavage. What size bra should I be looking for and where should I be looking? I am happy to help. I also make some style recommendations too. Sometimes there are some fabulous boutiques a little further out, but having access to a fitter as well as the ability to try the bras first would really help.

Have a great day! I love your blog posts. Thanks so much for sharing what you know about this subject. It really feels like a jungle to me. I wanted to ask you if you know anything about the Fantasie sizes.

Most of the time I wear a 65G European size. I recently started to order bras from UK and have figured out that a 65G should be a 30F. But I noticed on a tag on a couple of bras by Fantasie, that say: Do you know anything about this? And thanks again for sharing your knowledge. It has helped me a lot when picking bras.

I am glad the blog has helped you navigate the jungle. Eveden has two sets of tags out there on the marketplace, and I know at least one of them is wrong. However, I know that Fantasie sometimes just takes their cup size and applies it across the board, meaning they will say a UK F cup is also a US F cup. Their conversions other sizing systems are not always accurate and have raised a lot of questions here lately too. Hi, I am looking to buy a bra from Boux Avenue and I was wondering how their sizes run.

I measured myself and found myself to be 28 inches around the rib cage underneath the breasts and then 32 inches around the breasts. So I assume that would make me a 28D. I have bought a UK sized bra off Amazon before, the Cleo Neve Plunge t-shirt bra, but I found the band to be too tight and the straps set too wide apart, making the cup wires dig into my armpits.

I have a small rib cage so that bra was too wide. What would you say about buying bras from Boux Avenue? Hi Erica, I usually buy Fantasie 32 G which fits me well but want to try Wacaol would I need the same size or do the Wacaol bras come up smaller? The Wacoal 32G is smaller in the cup than the Fantasie 32G. Now, that said, Wacoal often cuts a pretty tight band, so you may be happier with a US 34H in their bras.

Hi Lynda My measurements say 35 around to cage above breasts Am I wearing correct size else please correct both UK and U. Hi Erika, I am confused. I measure a 28 underneath my breast but a 38 in bra band size fits me! That sounds like a pretty steep difference in measurement vs. Is it possible the 38 fits you best because you actually need a size like 28J or JJ but have sized up to ensure cup coverage? I did this myself as a teenager and college student. A 38DDD gave me coverage, but the band was hopelessly big.

These bras all hold the same volume, but their proportions are very different. It is not recommended to wear a bra any more than one sister size away from your ideal bra size. If the bra band is altered to be smaller, the way the cup fits will change and the straps also start out further.

Retrieved from " http: 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.

Bra sizes marked with the same color (placed in the same row) are sister sizes and do have about the same cup volume (actual cup size) as your usual bra size - and may fit you! So, if you i.e. are using bra size 34C, a 32D or a 36B may also fit your bust! See which bra sizes that have same cup volume in the bra sister size charts below. Remember: Different "bra sister sizes" can be used by the same woman (cup volume will fit). But it is no guarantee that all band sizes will fit. Bra sizes that are the same in volume are often referred to as “sister sizes”. The grey cells in the table below demonstrate how the sizes diagonally adjacent from the top right to the bottom left are the same in breast volume i.e. the same volume of breast tissue spread across different size rib cages (band sizes).
