I am 5'7, 140 lbs and ordered a US size 4. I am rather small chested and boob tape was required but the cowl neck really flattered my small chest. The dress is heavy, which I like, it feels well constructed. The gold shimmers beautifully because they are tiny rhinestones instead of itchy sequins. They also sewed multiple thin layers of fabric between the rhinestone exterior and your skin so no irritation or rubbing. The dress went down to the top of my foot which was perfect because I didn't trip when walking. Though, the hips were a tiny bit tight which made it difficult to dance.
