Very nice costume! I ordered a Women's Small, and I'm 5'5", around 115–118 lbs, and a B–C cup. It actually fits my smaller chest really well, which I appreciate since that's pretty rare! If you have a bigger chest, though, it might not fit as well. This is an amazing costume, and the accessories complement it nicelyThe only downside is how the wings and tail attach. They use bobby pins, which honestly don't work very well. I ended up removing mine and replacing them with double-sided Velcro, which works SO much betterThe tail is also a little too long for my liking, so I probably won't use it for my photoshoot, but overall I'm really happy with the costume and glad I got the wings working
