I find that Shoshanna dresses run TTS or slightly large. I actually bought one of her dresses a while back at BG and guess who was at the register?! Shoshanna herself!! She was really sweet (and damn, the woman is so slim I felt like a WWF wrestler in comparison!) and we talked for a while. She does design clothing for slim, yet bustier women (that's her whole thing) and I feel like her dresses sometimes have a bit too much extra material up top (especially since I'm just a B cup)... overall though, the fit is great. I hope you love your dress (it sounds beautiful!), PearlsnFlats! Please post pics once you receive it!
