My gf has gradually gained some weight in past 1 month due to sitting job basically but the problem is she is very much concerned about her breast size which has changed from 34 to 36 and now she is unable to identify her cup size as it is okay from band size but only the older bra cup is getting tight so we think that they are getting heavier as she is just 21 it is giving her sense of anxiety. What should we do to make them as they were earlier. Please suggest.
