An issue I have is what some of the guys wear: low jeans with boxers showing, taking their shirts off to show lower abdomenal hair, etc. Some are of the belief that girls have no visual temptation challenges. Not true. Modesty goes both ways.
I can see that side too. It irks me to see guys wearing too large pants with the "plumber" look. In our larger metropolitan area you see that a lot. I think though, that in my immediate locality, it isn't as much of an issue for the males to dress modestly. For the most part, they already are.
There are those guys around here who dress vey *differently* but I would not necessarily classify that with being immodest.
