Q: Ordered size small in blue. I'm about 5'8, 150 lbs with more of an athletic build. This dress fits perfectly. The color is more vibrant than I thought it would be but I love it. Fabric is pretty good quality and there is a little stretch in it, but very comfortable. Very happy with this purchase.

A: positive
