Well, as far as stage stuff goes, I...halfway do it (androgynous female in unisex clothes in a mostly male-dominated industry here), but not exactly. As for my opinion on others doing it...hey, whatever floats your boat. I've seen some people who look pretty awesome as the opposite gender, others who are just downright comical...but hey. You wear what you like, that's totally fine by me.

Way I see it though, crossdressing just for show should be confined to the stage, never done out on the streets. It kinda kills it for the people who just want to wear clothes designed for the opposite sex because they like them. :/
