Naw, I have no idea what I weigh. But provided the skirt is an elastic waist and has no constrained hip (like a tutu circle skirt or something), then yes, I fit into most. I think it's equivalent of about a size four in women's jeans, so it's not like I've gone anorexic. Once I can find my camera I'll put up a picture cos I'm rockin' the tutu look right now.
Okay, I just checked, at Old Navy (where most of my shit comes from now since I get it cheap), the girl's XL waist is 26", and my waist at the moment is, I think, 25 or 26. And I still wear a size six. So I'm not emaciated, I swear!
