Well, just like the heading says, I should have purchase my size (18) but I went up because of the sleeves in the picture, they looked somewhat tight and I wanted to be comfortable, but that was not the case at all, haha, the 2o had plenty of room, the fit was REALLY loose. Good thing I know how to sew, had to take it in.Now to find more dresses with pockets, you have no idea how much of a win that is.See full review
