I'm 5ft 1in and 117 lbs, I mostly wear small but the dress was underwhelming in terms of my expectations from the photo, the fitting and the price. I like my bodycon dresses to be tight fit and it felt large on me. I rarely wear extra small but for this dress try sizing down. Though I have to say the dress is the perfect length, comes right above the knee and the material is really nice and thick. Looks really nice in the picture with bright light, but when I tried it on not as pleased. If this is your style go for it again the material is really nice, but I would save the money for another dress nicer, and more tight fitting.
