Ok, so this dress is absolutely beautiful. I am 5'5 and weigh about 145; I have a little extra meat on my hips and butt. So for this dress, I would recommend sizing up. I originally got a medium (as medium is my typical size for clothing) and it was really tight around my hips. I exchanged for a large and it fit me so much better. The top half is a little big but easily managed and fixed. All in all, LOVE this dress and I plan to wear it many times in the future!
