I recently lost about 10 lbs. so I was excited to show off my curves in this dress. Well, it did not disappoint! The medium was perfect for me--I'm about 5'7, 132 lbs. It fit like a glove and I got a ton of compliments! It's definitely been worn a few times and you can tell that lots of use has impacted the elasticity, but it didn't really bother me.
