I ordered this in a size 8 and at 5'10", 135 lbs, it fit me perfectly. The neckline was a bit snug but was easy to get used to after a few times of trying it on. The hem sat just a little bit lower on me than on the model in the picture, but I didn't mind that. I was very happy with the quality of the materials and construction of the dress and would not hesitate to buy from this company again.
