Beautiful cocktail dress with a decent amount of stretch to it. The asymmetrical neckline is gorgeous. I received so many compliments on this dress. For reference: I'm 5'7", 150 lbs athletic build (muscular thighs and butt, small waist) size 4/6 in pants, typically a medium on top (36B/C). I ended up ordering a medium. The dress fits but it's definitely curve hugging (thank goodness for stretchy material!)! I would prefer it to be a little looser in the hips but ordering a large would have caused the top to be too big and the neck material wouldn't have looked right.. I ordered this for an evening event, so the tight dress was still appropriate. If I was willing to put more work into it, I could have ordered a large and had it tailored.
