This, and you can ban barely bend your knee at a 30 degree angle, so you're reduced to walking around in pain, or doing the penguin walk everywhere. For girls, it's fine. Guys, ew.
Skinny jeans on guys are a nono. I always make fun of my guy friends that wear skinny jeans, and I make even more fun of them if they're wearing like bright green or purple skinny jeans.
It's okay on girls, I guess. To be honest, though, I much rather prefer sexy cargo pants on either gender <3
