Just got this dress and I was so excited to try it on. I rented a small and a medium for my backup (suggestion was to go up a size). I should have actually gone down a size for my backup. The ruching on this dress makes it a tad loose. The dress fit great across my shoulders and my arms but, I wish it would have been tighter around my waist. If you have a narrow waist and you are thin like me, I would suggest going with an extra small. The color is beautiful and the material isn't too thin. We'll see if this dress is a hit.
