My first pair of Cosabella's and I couldn't be more pleased. I ordered the Medium (I'm between a small and a Medium) and I *think* I could have gone with the small. The elastic is very forgiving. They seem very well made so I'm anticipating that they will hold up well in the wash (cold cycle, delicates, hang dry) but will post an update if they fail miserably after a month or two of washing/wearing.
