Bra sizes for teenage girls

Teenage bras start from cup AA and go up, depending on the brand, to cup B.

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.

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 of girl’s underwear on Amazon has a bra or bra top for any girl, regardless of what size she is.

How many bras do I need?

Starting with 3 or 4 bras will do. You might need a bigger bra size soon if you’re still growing. As a young girl, your bra size can change in a short time.

Step 1 Measure your underbust
Hold the tape under your breasts and write down the inches or centimeters.

Step 2 Measure your bust
Hold the measuring tape around the fullest part of your breasts. Don’t pull the tape too tight. Write down the inches or centimeters.

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

Step 3 Find your best bra size in a bra size chart.

Always start with choosing your best bra band size first. Go from there to decide on your cup size.

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
