You know to be honest with the amount of focus on personalized style and character customization that's been put on it in the last few years, I'm surprised tf2 doesn't have female versions of the classes yet.
There have been some developed by chemicalalia that look fairly good, although it's pretty unlikely they ever get added. Some have cited the addition of extra silhouettes to distinguish between as a major factor, others have warned that hitboxs may be different sizes or not match up with the visible models, both serious problems for a class based competitive game.
Personally I just think it would break the game. When they added a second Misc item slot (for cosmetic badges and whatnot) the whole game went buggy as hell, and servers were crashing left and right. It was never intended to have as much extra crap (see: hats) added to it as has been, and I think it just can't take no more.
