Some people like to look good, damn good, and they like to do it in as many different ways as possible while they kick ass. Take a character with those traits and you've got the Action Fashionista.
The Action Fashionistas are some type of badass partly characterized by the vastness of their wardrobe. While they may have a standardized costume or uniform, they almost never seem to wear it to its strictest definition. The vast majority of their screentime features them with different articles of clothing or major alterations of the same outfit. (For example, what was a blouse in one scene has become chainmail in a later scene, a mink coat in another, and a pink-and-white jacket in another.)
