I wanted to love this dress. The material is surprisingly soft. But I went with my true size which is a small in literally everything from dresses to shirts and pants. Usually a size 4 in most dresses. However, it's a little tight under the chest (I'm a size 34A for reference), and the slip is extremely short in the back. It literally stops at the bottom of my buttocks so if I move AT ALL you can see butt cheeks lol. I would recommend this dress but definitely size up one without a doubt.
