Runs small!
I am usually a size 0 maybe 2 but sized up to the small (4/6) because it's a tighter-fitting dress. It was so tight around the butt and was like a push-up bra on the top! Not in a flattering way though, it was riding up everywhere if I tried to walk. So, maybe size up 2 sizes if you buy. I just gave up though and went for a different style.
