1. How will I know if I need an AA cup?

It is easy for women with small boobs to go for the wrong cup size.

  • not all bra size charts have AAA and AA cups listed
  • you might be advised a wrong cup size
  • you might never have had a well-fitted bra, wearing bad-fitted A or B cups because you’ve always been wearing this

Bra sizes can be close together so it’s easy to go wrong

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.

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. 

2. The best AA cup bra brands

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

There is not an abundance of AA cup bras in the stores. Or when they do have an AA cup bra, it’s not always the grown-up bra you’re looking for.

As a teenage girl, you can wear bra tops or you might go for your first bra with an actual cup size. It could be you need an AA cup for your first bra. But some girls need a slightly bigger cup, like an A, B, or C.

Not sure about your bra size at the moment?

If your bra doesn’t feel comfortable it is time to check your bra size.

A well-fitted bra certainly feels comfortable and makes you stop thinking and touching the bra all day long. A well-fitted bra makes you feel confident and your clothes look better because you feel and look better in them.
