It's not the size that matters... that's the right expression isn't it? Relax, you'll see the entire gambit from flat as a board to ones that would give you a concussion if you aren't careful.
I am a b cup also and do enjoy going topless at TTR and I don't ware a top don't worry at all. The way we look at it is a couple of ways - more than a hand full is a waste... also we can tan below our boobs lol.... and they don't get in the way as much as your DD's did. Have fun either way all is good!!!
Boobs are just like coffee...sometimes you really enjoy having a tiny expresso cup, some other times a regular cup mocha, some other times an extra large cup of Frapuccino... in the end coffee is always good regardless of the cup you are served... same applies to boobs!
