All you need is a white sweater, glasses, and temporary blue dye. Then when you're all partied out, you can say, "I'm too sad to walk. Just give me a few... hours?"
2 Effie from The Hunger Games
Panem's resident (and only?) fashion girl has so many looks you can choose from. You can also check out our makeup tutorial here.

Excited for Suicide Squad to come out next year? Dress up as this hell-raiser and make her proud by going all out.
5 A Jedi from Star Wars
The perfect excuse to have lightsaber duels with your friends.
6 Liv from iZombie
The best part is that you can bring a snack (brain-like shrimps doused with hot sauce) and say it's part of your costume. Yum!
7 Chanel from Scream Queens
Better yet, convince your friends to come as the Chanels—it’ll make for a killer night.
8 Kara from Supergirl
Perfect timing because the show premieres just a few days before Halloween night.
9 Finn or Fionna from Adventure Time
Whether you go as the original adventurer or the gender-swapped version from the Ice King's very own fanfic, you're sure to have a mathematical time. Double the fun by convincing your bestie to dress up as Jake or Cake!
10 Leah from On the Wings of Love
Leah's SF look is great for a last-minute costume idea: just throw on some layers, put your hair up, and make sure your brows are on fleek. Who knows—maybe you'll even run into your very own Clark!
