A cup



The A cup is just one of the smaller cup sizes

A cup bras are generally considered the smallest cup size available. But we know their not.

They have the good companion of AAA and AA cups. And there’s more good news! There is a new cup size AAAA by Dainty Lady, a lingerie company from the UK.

How small is a cup size A?

Bras come in different band sizes and in different cup volumes. Cup size A is one of the smaller cup sizes available. The smallest cup size is AAAA cup.
If we talk about petite bras on brasforsmallcups.com we mean AAAA to B and sometimes C cups.

If you’re not happy with your current bra size it could well mean you need one of these cups: AAAA, AAA, AA, A, B or C.

Don’t let this confuse you. It is important for women with small breasts to realize that the difference between these cup sizes isn’t always that big as you might think. Let me give you an example.

This woman is wearing a 40C bra at the moment. She is not happy with the cups, they are to too big and she finds the band size a bit too tight.
Going up a band size would be a 42 band. When going up a band size the cup volume will automatically change too. A bra in 42C has more cup volume as a bra in 40C. So this women has to go down at least one cup size. She might wanna try 42B and 42A.

A little change in measurements can change your bra size

Maybe you wear an A cup bra and are a bra LOVER already. Meaning you’re wearing your right bra size.

If not? It is time to check up on your sizes. You would have to measure your underbust and your bust size. With these measurements, you can check out this size chart for your best bra size.

Remember that bras have sister sizes. Meaning you could well fit more than one bra size. Especially if you’re in between two possible band sizes you could well have different cup sizes that fit you just fine. For example, a bra 80A has the same cup volume as a bra 75B.

I own bras in 3 different sizes ( 34AA, 34A and 36AAA – and they all fit me just fine. Depending on the type of bra and the brand I choose different sizes.


What happens with my cup size if I change the band size?

Bra sizing is not an exact science. It is a process of taking good measurements and finding your true bra size (and checking a bra size chart that includes all small cups).

Changing you band size will change your cup volume as well

Especially if you are in between two band sizes it is likely you fit more than one size. They are called sister sizes. Your current bra size has ‘sister sizes’ which are alternate sizes where the cup volume stays the same even though the band size and cup letter changes. 

Let’s say your wearing a 38A bra at this moment

  • if your band size is close to 36, sister size 36B might be a good fit
  • when your band size is close to 38, sister size 40AA might be a good fit.

If you’re happy with the fit of your cups, you wouldn’t want to change this. But what if you’re not happy with your band? And find it either too tight or too loose?

I’ll best explain this by an example.

You wear a 38A bra but want a wider band size.

  • You choose 40AA (wider band but keeping the same cup size)
  • So it’s up in the band, down in the cup (to keep the same cup volume).

You wear a 38A cup but want a smaller band size.

  • You choose 36B (smaller band but keeping the same cup size)
  • So it’s down in the band, up in the cup (to keep the same cup volume).
