# How to determine bra size?

Topic: What is the sister size to 34c
June 16, 2019 / By Ashlyn
Question: I know this has been asked before, but I have seen different answers so I am confused. I normally wear a 34 B but think I am wearing the wrong size. My measurements are: 29 inch under-bust, 35 inch bust. So what is my size? Thanks a lot.

Sounds like you are wearing the wrong size by your measurements. Your band mesurement is 29 so that means a 28 or 30 band. Your bust is 6 inches different to your band measurement so that equals an E cup. 1 inch equals a cup. Measuring isnt an exact science it is more like a starting point. Start with a 28E. The band must be snug and parallel to the ground. If it is too tight, try a 30DD. This is the same cup volume but with a looser band. It is the sister size. All these sizes have the same cup volume 28E 30DD 32D 34C 36B 38A. So a 28E is only 1 cup size different to a 34B even though the 28E sounds much larger. It isnt. The band is much tighter though. Get the band right first, most of the support comes from the band. Then think about the cups.If the cups have gaps, go up a cup until you get the right fit. If the cups have bulges go down a cup until you get the right fit. You need to find a store that stocks a large range of sizes so you can be sure to get the right size. Good luck!

I'm 16 and 5'5 as well... You are the perfect weight, you have smaller feet, and you have a larger bra size but there's no average in that case. 16 year old girls have anywhere from A to C cup (maybe D) and that doesn't mean anything in relation to your height or anything.

if your're petie you can't expect to be the average size for anything lol. height also depends on your're parents genes!.... a 16 year old female should be about 110 pounds and about 5'4-5'6 average unless tallness is in genes.. shoe size goes along with height... i say about 7. i'm 19 and i weigh 100 and i'm only 5'3 and shoe size 7 7/12 .. everyone is different all goes back to genes

I think you are more likely a 34C. You shouldn't have any breast exposed under your arm, or between the cups. If you do your bra is too small. Also, it shows through when you wear a thinner top. The letter is the cup size and the number is the size around your front & back. Good Luck:)

You should go by your ribcage which is your under bust. Your actual bust size however is your cup size. I think maybe size 32B. But just fyi, different bras can fit differently, so you'll know when you try them on.

i dont know the average. and you shouldnt base yourself on the average. seeing that everyones uniquely different, buying the average size may end up leaving you with a ring too big or even worse, one thats too small. and then in that case you cant even wear it at all! go to a piercer and ask them to measure the diameter of your lip. they will tell you the size and most likely, you'll be able to buy the jewelry you want at your piercers.
