I F'N love this dress. I was pretty skeptical it'd fit like the pictures, but after reading lots of reviews I decided to commit. So happy I did. I ordered a small, I'm 5'5, 130 lbs, A cup. This fit like a dream! I got black, it's gorgeous, I'l likely buy others in different colors. The material is fantastic, comfy, and is stretchy so it's flattering in all the right ways. Also seems like there would be wiggle room to bounce in  between sizes if you're not sure what size to get.. The criss cross section covers my tiny chest perfectly and I have no reason to wear a bra (and it's not see through). The length is great also, long enough that I don't have to worry about my hoo-ha showing if I bend over. My belly button is covered which I'm a huge fan of. I'm pretty obsessed with this dress. I got an oo la la from the husband.
