A spoof of...what, exactly?
Leather is not my thing, unless we are talking a leather jockstrap that has been sweated in several (dozen, hundred ;-) ) times.
But lots of guys, like @honcho , do like it so I can't fault an escort for wearing leather in a picture or two. As long as he can go without wearing it when a client isn't into it there really is no harm.
Please, do tell if you have taken the plunge.
