Does this not trike anyone else as being a rather odd question? I don't recall having ever noticed what anyone else was wearing - nor would I have cared.
I dont see how it is odd.
I think many people that are going to the range for the first time wonder what they should wear.
I dont really look at what others people wear at the range but I cannot not notice a guy in full combat tacticool gear shooting next to me, same way for guys wearing a dress.
I usually go to the range COMMANDO
