5'7", 150-155lbs ordered a medium in the green. I love the material. Some say it looks cheap, but I thought the material was nice. It fits, but the pants are way tighter than I wanted. I'm hoping they stretch with wear, but even the band at the top is tight, I doubt it will stretch. The top is slightly oversized, but I was wanting it bigger. I normally wear a medium or small in things, but I wish I would have got a large in this.See full review
