I'm 5'7 160lbs.. I bought this in a medium and it fit comfortably. It has a little strength to it if you're more curvy in the hips. Was a great buy!

The colors are vibrant, just as the picture, but the look and fit of the dress is not what I expected. I am a sz12 (XL-196lbs) & purchased an XL, could have definitely gotten a L, possibly a M. The top half runs large, bottom half, fit comfortable, not to tight or loose.
