Finding this very interesting, I have my normal size and a size up at home at the moment, and am about to order two sizes up! The reviews all say to size up a size or two as well. My normal size fits, I just don't like HOW it fits... certainly not like the model. I feel very lumpy in them. Maybe they just aren't for me.
I might try the Gap ones as well, esp the white.
Looking forward to seeing you in yours...
