A burka isn't skin tight. Maybe you mean a leotard, or one piece bikini. Either way all the female characters are starting to look like the same thing with a different costume on. Its time to buy a new template.
Le's jus' go look at Solid Snake and see how tight his clothing is.
Batman technically has a cape....
As a general rule of thumb, if you're kicking ass and taking names, you don't wear clothing that can get in the way.
