Rules over here do not allow players to wear tights, but knee-high socks and baggy shorts are alright. So how do you find out what a player is wearing when you can't see any skin?!
The guy in the pic had to take off his tights at halftime, since we found out he wore tights only when he tucked his shirt back in and therefore pulled his shorts down first.
Makes you look stupid approaching a player before tip-off, asking what he's wearing underneath his shorts
