This dress was a perfect, snug fit. The downside is that the sequins fall off easily and it might be one of those that you only wear once (maybe twice)...but for the cheaper price, it's perfect. I'm 5'8" and I average around 123-125lbs and wear a 32DD, and zipping the dress got tougher because of my chest. I ordered a small and still feel like I have room in my stomach to eat and move around. It's a sexy, but tasteful, mini-dress, which is what I wanted to wear to my boyfriend's company holiday party - and the dress definitely got his seal of approval!
