since my childhood days I get to notice whenever two girls or women are fighting, they live to strip themselve unclad..............now the question is why do ladies do that?

Very funny

Well I think because they have no other pride. Hence protect it with everything. But seriously I don't know. Only a lady can actually tell you why?

In those days when our society was sane, u dare not expose ur nudity to the public otherwise ur image will be seriously dented

So they are always eager to dent their rival's image by exposing the booby & yanch
