Katiss Everdeen from The Hunger Games
Okay, so Katniss is the lead of one of the coolest YA franchises in recent memory. It also doesn’t hurt that her outfit looks great but is relatively simple! You need a black shirt, a jacket (either black or brown, preferably leather), black boots, and black pants. A bow would be nice, too, but some conventions won’t let you come in with strung bows, because they’re dangerous! Anyway, don’t be afraid to peruse the local thrift store for a cool jacket you can tweak for your Katniss garb.
