As for anime, I've been Lychee and Tsubasa, both minor characters from Ranma 1/2. Technically, Tsubasa isn't crossplay, but crossdressing, because Tsubasa is a boy who crossdresses.
I've also been a gothic lolita girl and Columbia from RHPS.
I have a special album into which I have placed my female costumes specifically. http://images.cosplay.com/showgallery.php?cat=7544
