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 cup size AA – C. 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).

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 will I know which bra size fits me?

To decide on your bra cup size you will need to take two measurements. You can measure yourself at home, it is not difficult. Of course, you ask someone to help you with your measurements.

There are only 3 steps really.

Step 1 measure your underbust

Step 2 measure you bust

You need a measuring tape a mirror to check if you’re holding the tape horizontal.

Measure your underbust (hold the tape under your breasts) and write down the inches or centimeters.

Measure your bust size. Hold the measuring tape around the fullest part of your breasts. Don’t pull the tape too tight. Write down the inches or centimeters.

Step 3 Find your best bra size in bra size chart. Or you can use our handy bra size calculator.

Many girls and women 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).

Where to buy the best teenage bras?

Once you know which bra size to choose you can start shopping and find the bra you like.

For different reasons, you need a couple of bras in your drawer.

  • You need 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.

This 95% cotton wired bra of Boobs & Bloomers has lightly padded cups, 7 colors to choose from. The bra has flexible wires and comes with a clip so you can wear the bra as a racerback as well.
