Odd number? Add 5. Even number? Add 4.
For example — if you measured 29” and add 5, you get 34”. This is your band size!
1. Wrap a tape measure around the fullest part of your bust and take note.
2. Round to the nearest whole number.
3. Subtract your band size from your bust size and voila! This determines your cup size.
For example — if your band measured to 32, you would subtract 32 from 34 to get 2!
Put your band size and cup size together and now you have your bra size!
Our example comes out to be a 34B.
