So, I'm probably not going to be changing my HA anytime soon, with one exception.

Pants.

These light-blue short overalls are cute, and I would have loved if they came in a darker color that matched the color scheme I was going for, but...Nope. So, I need some help.

I'm looking for a bottoms-layer'ed item that matches this cholor scheme (primarily the grey/blue with black, the accents of red aren't necessary for the bottoms), ends above the knee, and seems to fit with the whole...idea of this weird. Horned. Person.

Thank you very much in advance! I'd also accept other suggestions, but namely I'm looking for pants.
