I wanted to like this dress, especially given how it looks on the model, but nothing, absolutely nothing about it was right. I'm 5'8", 126 lbs, athletic built, so according to the reviews and the chart, I ordered a size 8.
The lenght: At 5'8", I'm certainly not super-tall, but the skirt barely covered my feet - barefoot, now imagine how awkward it would look if I wore heels?
The waist: The one part that fit, but the zipper has a kink in it, so it wouldn't zip up.
The chest: Oh, the chest. The cleavage looked at least 2 inches deeper than in the pictures, and the cups were ginormous. I'm a 32C, not big, but not tiny, and those cups would have easily been able to hold a DD, if not more.
The halterneck: Obviously made for someone with a long torso, since I could have easily wrapped this thing around my neck and close it in the front.
Bottom line: The fabric is quite nice, but that's where the positives for this dress end. Spare yourself the hassle and look elsewhere.
