I always thought I was a 34B (not a lot of boob) but then realised a 32C fit better.
Recently, having hit 50 and having gained half a stone, my boobs seem to fall out..if one is perfectly in the cup the other cup is only half covering, with one nipple attempting to make a bid for freedom!
I tried a 32D but while it covers all, it's a bit loose on one side (one boob is a little smaller) What am I doing wrong? It feels like my boobs have moved futher apart!!!! (in case it makes any difference I'm about 5ft 7 and 9 stone 8, having gained half a stone this year :/ )
