Bra sizes for teenage girls

Teenage bras start from cup AA and go up, depending on the brand, to a cup B, or C. You could say the larger your breasts the bigger cup size you need.

As a teenage girl, it could be you need a cup AA, but it can also be you need an A, B or C cup. Many grown-up women also still wear the smaller cup sizes AA-B. All girls and women have unique bodies and breasts.

Remember that there’s no such thing as being too small or too big. Nature comes in all sizes (and this will always be like this).

Your first cup size may start with A, B, or C

It might be that your breasts are (still) too small for a cup AA. You then want to look for bras and bra tops that come in sizes starting from x-small. The collection girls underwear on Amazon has a bra or bra top for any girl, regardless of what size she is.

How many bras do I need & how to take care of them?

  • You need different bras for different occasions, like school or doing sports.
  • You can wear different styles depending on what you wear, for example, a racerback style underneath your summer dress or low cut top.
  • Did you know that your bra needs a rest after wearing it? In this way, the elastic fiber will regain its shape. If you have a couple of bras you can rotate them.
  • Your bras need to be washed regularly by hand. This keeps the fibers clean and more elastic.

How to measure my first bra?

Many girls are just in between two band sizes or cup sizes. So you might have doubts about which bra size to choose. Just play around a bit with the measurements and maybe measure a couple of times.

Going up or down a band size will change the cup volume as well. If you want to keep the same cup volume you would have to go up or down a cup size as well. For example, 75A and 70B bras have the same cup volume. (75A and 80A do not have the same cup volume).
