I believe in a well-fitted bra for every woman

Going up or down a band size will change the volume of the cups. The bra 38AA has less volume as the bra in 40AA. The bras 38AA and 36A have 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

Women with small breasts should check a bra size chart (or calculator) that includes all small cup sizes. I know many women wear the wrong cup thinking cup A is the best for them. Not really haven’t checked their sizes properly.
