1. Frame Size
Your frame size is the diameter around your chest, below your breasts. Measure around your ribcage directly under your breasts.
2. Breast Size
Now measure around your chest, over and including the fullest part of your breast.
For larger breast, get this measurement while wearing a bra.
How the Measurement Works
The diameter around your chest below your breasts.
2. Bra Size
Add 5 to your Frame size.
If the number you get is odd, round up to the next even number.
For example, if your frame size is 20 inches, when you add 5 to this you get 25 inches. You should therefore round up to the even number, which is 26 inches (bras only come in even numbers).
3. Breast Size
The diameter around your chest, over and including the fullest part of your breast.
4. Cup Size

When the right bra size still isn't right !
If your bra still doesn't feel right, the best thing to is to try on deferent brands, and vary the size a bit. Make sure the bra strap doesn't cut into your shoulders, and make sure your breasts don't hang out of the bottom, or sides of the bra.
The best rule is, if it just doesn't feel right, try another bra.
Bra sizes can vary a lot depending on the type of bra, and even the brand. The best thing to do is go into the changing room, and try on a number of different bras.
Once you find a bra you like, jump around a little to see if the bra gives you the proper support, lean forward in the mirror to see if the cups keep your breasts where you want them to be. A new bra should fasten at the middle or last hook, because the material will stretch with wear.
The best thing to remember is comfort; a bra that scratchy or tight will drive you crazy by the end of the school day.
