I am 5"6 140lbs and I got it in a medium. The dress is true to size, as I wear a medium in most of Fashion Nova clothes. it looks just like the picture or better. The material is nice and feels good on the skin. The dress has a lot of stretch, if I had gotten a large I don't think it would have held me in the way it did. defiantly hugged my curves but not to tight. it came approximately 7 to 8 inches above my knee. The bottom has a lining and I didn't have any problem with it crawling up. Perfect for a girls night out or date night. I get my deliveries in 2 days in the USA, no additional cost, if I order on Tuesday It usually arrive on Thursday.
