I’m lopsided! I have one breast that is one full cup larger than the other. For some reason I never really noticed it (I wear sports bras most of the time). Until I was getting fitted for a dress by my mother. My mom would make an adjustment to the dress, I’d try it on and it would be all wonky on one side. We did this about three times, before we realized that it was my breasts that were making it fit weird.
