Super cute dress. I bought a small, but I wish I would have gone with a medium. It fits everywhere but the chest. I'm a 34 B/C and the buttons on the chest don't want to stay closed. I usually wind up layering the dress under a sweater to prevent wardrobe malfunctions (layering it is actually really cute, though). Also, the blue is quite a bit darker than it looks in the photo - closer to navy blue.
