I am 5'7" and 135 lbs. I got a size 6. I usually wear a 4-6 in street clothes, and a 29 in designer jeans. The fabric is really cool and overall it's a really nice dress. However, it's a tough dress to wear for me. I have a 34B. With the straight across neckline, I had some "armpit fat" issues, which caused me to send this dress back (for almost $200 I want it to be perfect!). The blush shade seemed like it would be pretty flattering for everyone. The rouching was flattering though, and had great fit in the waist.
