It's really a matter of preference.
Personally, I find the catfight is much more exciting and sensual when women are dressed in sexy clothes, like a dress, a skirt, leather pants or tight jeans to fight, and they pulling their clothes in the struggle to reveal their underwear, and finally their nakedness. But see naked from the start, I think it's a bit boring. It spoils some of the fun. But this is my personal opinion 
I have a Joan wise fight on vhs between a blonde and a brunette. Sorry, but it's been a while since I watched it and I don't remember their names. But the brunette was wearing a black dress and the blonde in what looked like a short white nightgown with white bra and pants underneath. The brunette dominated the blonde but instead of stripping her naked she just ripped her clothes apart so they were left hanging from her body. Even her pants were still on but not covering anything up.
The brunette straddled the blonde and toyed with her. She gave her wedgies and pulled her panties to one side exposing her pussy. She was trashing and taunting the blonde the whole time, calling her a dirty little blonde c##t and asking her if she was enjoying it. Seeing a girl pinned like that, whimpering and struggling with her clothes hanging off her body was so hot. Hotter than if she was naked.
