AA cup bras

AA cup bras are just what many small breasted women need. And I know many of them (still) wear an A, B, or C cup instead.

How will I know if I need an AA cup?

As I keep mentioning, petite busted women are everywhere. Even though it might sometimes feel you’re one of a few.

AA cup bras are getting more and more common. And that’s a good thing. Boobs come as small as they like. It has always been this way and it will never change. Even though boobs may only seem to get bigger, us petite girls are everywhere.

It is easy for women with small boobs to go for the wrong size when you don’t pay enough attention to measuring your own bust size and band size.

You might need an AA cup bra if your current bra size cup A, B, or C is too big.

But it is not just going down (or up) a cup size. The first thing you have to decide on is your band size.

This seems simple. But let me show you what happens with a few examples.

  • you wear 38A and find the cups too big, your band size feels fine and firm
    » you might wanna try 38AA or 38AAA.
  • you wear 36B and find the cups too big, your band size is a too loose
    » you might wanna try 34B or 34A
  • you wear 40C and find the cups too big, your band size is too tight
    » you might wanna try 42B or 42A

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.

Depending on the bra style and brand, you could wear different bra sizes and they all fit you just fine.

I wear 34A, 34AA, and 36AAA myself. These sizes all fit me. Through the years I learned what to choose depending on the bra style and the bra brand.
