This bugs me too. I kept the small anyway, even though it's a little too big.
Oh really? Crap. I wonder if it will fit me okay then? I'm bigger right now but by summer I'm guessing I'll be closer to my normal weight.
We're the same weight but you're taller and the main issue is that it's a bit long in the front on me but it kinda bags in some areas too. Not enough that it looks horrible though!
