Going up or down a band size will change the volume of the cups

a 38AA bra has less cup volume as a 40AA bra
a 38AA bra and a 36A bra have the same cup volume

Changing your band size? Go down or up a cup size as well if you want to keep the same cup volume.

  • it’s normal that you might fit more than one bra size, and both sizes fit you just fine
  • it is also a matter of personal preferences when choosing your bra size
  • some women really dislike a tight band of the bra and tend to choose a looser band
  • it is a thing of trial and error
  • you might have 1 best bra size
  • you might have 2 or maybe 3 sizes that fit you fine, depending on the model and brand of the bra
