How will I know what bra size to get?

If you realize that (according to researches) 60 to 80 percent of women do not wear their right bra size you might think, how come? Well, it is not uncommon to wear a bad-fitted bra for too long. It happened to me for many years.

Besides the fact that we may have never worn a well-fitted bra before, there’s also the fact that many us need different bra sizes because of changes in our body and breasts »

We all know that a bad-fitted bra will not give us confidence. It is not a nice feeling touching your bra all day long. The good thing is! It only takes about 10 minutes to find your best bra size.

See our measuring guide on all topics »

Only a small difference in measurements could mean you need a B, A, or an AA cup. It’s that close. Also know that when changing your bra band size so will the cup volume. A bra in 70B does not have the same cup size as a bra in 75B. The bras 70B and 75A do have the same cup volume.

First, find the band size that fits your underbust. And secondly, find your matching cup size.

Many women are in between two possible sizes. Which bra size would you choose then?

For example:
your under bust measurement is 77 cm
your bust size measurement is 86 cm
the best bra size would be 34A

but what if you feel your bust measurement could as well be 78 or 79? You might wanna choose 36 as your band size. Maybe you experience the band size being too tight on you. Remember that when going up a band size so will your cup volume. Bras 34A and 36A do not have the same cup size. So if you want a larger band and keep the same cup volume go from 34A to 36AA.

In the end, 2 different bra sizes actually may fit you just fine. Read more ‘Do I have a bra sister size?’ »
