I love this dress. Little tight. Boob part you have to tape the girls up. Very short dress, no stretch. I wouldn't say size up. It has a funny fit. I have wide hips so the top is fine, hip part is little tight. Nothing spanks can't fix. No material was falling off. I think I'll have a few wears. The zipper is cheap.
