Received my dress today and I of course had to try it on right away. I'm 5'7, and around 155 pounds. I took my measurements and compared them to the sizing chart. Ordered a size 12. It fits almost perfectly. The shoulder straps are slightly too big. That's all I'll need to have altered. I am beyond happy with this dress. The price was amazing and I'm surprised by the quality. In this case I got more than what I paid for.
