Fits well, I am only a B cup, so it fit my chest decently. Didn't wear the belt with it, mainly because I thought it made the dress look more casual. I really liked it though. I'm pretty short, too, so It touched the top of my knee. The flyaways in the back don't get in the way either. Women with bigger chests may want to be cautious of this dress. PS I wore this when I was a size 12.
