When I was in high school (early nineties), all the guys wore short black shorts (uniform) except for one guy I had a crush on who wore longer (almost to the knee) black courdory shorts. I couldn't find any made of coudory but I got black shorts that were the same length and they really showed off my legs better and, suddenly, just about every guy in my high school was wearing the same length shorts. I have to wear longer shorts now though because, when I wear the shorter kind, my cock hangs out of the leg.
