SISTER SIZING INFORMATION
Bras sizing doesn't work the same way as clothing sizing as the band size varies with the size of the cup like a ratio. If you go up a band size, you could go down a cup size and similarly, if you go down a band size, you could go up a cup size.
e.g. if you're a 12A, you could also fit a 10B or 8C
