This made the dress hard to zip a little. I got it zipped with the help of a friend. Im 5'2 and 100 pounds. The 0 fit the best but is tight if the boob area. I could not wear a bra with the dress. But it was okay because the top is tight. The 2 was easier to zip but wasn't in as good of conditIon as the 0. Plus it didn't fit as well or look as flattering. Also, they are Both the same length.
