This dress is absolutely stunning. I wouldn’t necessarily say that this runs small. I found it ran true to the size chart.I am typically a size 2 in pants and a 4 or 6 in a dress or jacket/ blazer. My measurements are 37-27-37 and I wear a 36C bra. I ordered a 6 because of the bust and was concerned it would be too tight. However, it fits perfectly, but would say someone who wears an A or a B cup would find it a little big. If a D cup, would probably still be OK if overall not broader than the 37 measurement but would likely show more cleavage. I think a 38 might be pushing it and anything under 35 without a bigger cup size would be too big.The waist is a little snug when zipping it. But once zipped all the way up and adjusted to lay properly, it fit perfectly. In fact, it looks just like the picture on me and it really shows the curves making my waist look really tiny. I do plan to lose about 5 pounds (128 now and 5’7″) which would bring my waist down to a 26 or 26 1/2 which would make sure that the zipper doesn’t pull at all, since I don’t have any wiggle room in the waist. The hips definitely are fine and an inch up or down at 36 or 38 would still work fine.I’m not planning to wear this until September when we go to the Caribbean, but didn’t want to take the chance of it not being available because I absolutely love it. The leopard print is the softest satin. The black isn’t quite as soft or shiny, but still beautiful with some sheen which actually makes the leopard stand out even more. And the rhinestones at the waist are gorgeous.
