I'm 5'6, 135lbs. I ordered a medium in purple. I would have fit the small, but I prefer my clothes to be a little loose. The material is thin, but soft. Like most dresses made out of this material, it shows all the curves and lines. The color is great and it is not see through. I think its a tad long, but maxi dresses are supposed to be. I would recommend this for causal wear as it is suggested in the item listing. Perfect for hanging out with friends, but not to impress anyone, in my opinion. A way to feel feminine but still feel like your in loungewear. If the material was a little thicker it would be perfect- I don't think this will last too long. I would not pay full price for this- I got it as a lightning deal. Overall I am happy with my purchase. Thank you for reading.
