Amazing dress! I ordered both the blue and the black in size large. The black is amazing. The blue fits like it is about a size smaller, and is a lot shorter. I wear a size 10 in most dresses. I will return the blue. I am contemplating re-ordering and sizing up. There is mixed reviews on size, and I am going to guess that is because depending on the color, the dress size can differ. I would recommend ordering a couple sizes and return what doesn't fit. Free returns so why not???
