More seriously…. the obvious ones are,
Pro of clothing… armor, pockets for carrying things, concealment, first barrier of defense against something like acid, or a hostile environment
Con of clothing… something an enemy can hold onto, restrain and choke.
If we take something like a school/cat fight where clothes get ripped off, but neither stops due to the indecent exposure? Flesh would be tougher to grip, maybe they go for the breasts? Certainly, urination or defecation during the match could be used, offensively or for shame depending on the person’s level of control or fear. (Which is more or less the limit of internet “research” videos can direct me…. )
