Cross-dressing

Cross-dressing was the act of wearing items of clothing commonly associated with alternative genders. As noted by Rose Tyler, Slist Fayflut Marteveerthon Slitheen was a "cross-dressing Slitheen"; though a female, she wore a synthetic skin suit based on the image of the male Ninth Doctor. Rose quipped that Jack Harkness would "love [her]" for that. (COMIC: Doctormania)

A matriarch of the clan Klep-Clotch Slitheen wore a suit made from the skin of Sir Edward Scott Cameron. (AUDIO: Death on the Mile)
