For many women, that was also probably the last time they ever got their bra size measured.
There are ways for you to measure your bra size in the comfort of your own home.
All you need is a standard measuring tape.

When it feels right, round up on the tape measure to the next whole number.
If you get an odd number, add five to get your band size.
For even numbers, add four.

Now it’s time to measure the cup size.
Put the measuring tape under your shoulder blades and bring it around to the fullest part of your chest.
This will most likely be at the nipples (viaCosmopolitan).

Round up the size and subtract the band size from it.
If you got one inch, that’s an A cup.
Two inches is a B cup, three inches is a C cup, and so on.
The brand is carried at Target, Nordstrom, and Amazon.
If you’ve never been able to find your cup size in stores, try shopping atBare Necessities.
