Bought this lovely dress, but found another dress instead. Missed the deadline to return it at J.Crew. Good news for you! It's backordered on J.Crew until November.
I'm 5'8 & 140lbs and usually a street size 6. This four fits me well even though I have a 34 D chest.
Girls who are smaller up top, don't be afraid to size down unless you are very, very pear shaped. I don't have narrow hips & the flowy skirt fits just fine.
I'm also selling the bouquet length veil for $200. It's used, but in like-new condition. Seriously no reason to buy either of these new...they're perfect.
