I came here to get re-sized. I had a young girl help me out and she measured me and after doing her fancy shmancy bra math she came to the conclusion that I was an A cup. Errr. Wrong. I couldn't get both cups in an A cup bra to cover one of my boobs. I laugh and inform her that she is mistaken and to try again. I even told her what I was and now what I think I am. She proceeds to argue with me as if I have no knowledge about boobs. I wanted to tell her that I have about 10 years more boob experience than she does, but I felt like I was getting nowhere.
Finally, she grew a brain and asked her manager to help her. The manager came over and before she even measured me she told me what size she thought I was (from just a glance) and she was spot on.
I bought a couple of bras, but never again will I ask them for size help. Maybe if they put them through some type of boob training course, but I'd have to see the diplomas on the wall.
