I'm 5'1, 126lbs and I ordered a small. It fit well but it was too long which I expected since I have to get everything hemmed. The material feels nice on. I think this was a better piece than the price I paid.

I absolutely love this outfit. I am 4'11 and weighs 111 lbs. I ordered extra small and had the length altered so mines would look like the model. It fits perfect. I have worn it to two different events and received a ton of compliments. The fabric feels great, too. I love it so much, I'm about to order a different color.
