Nail this Gossip Girl's look with a polished and preppy dress. Bonus points if you find a coworker to be your Serena or Chuck.
4. A Modern Disney Princess
Apple Accesories, $15, Modcloth | Big Red Bows, $18, Kate Spade
I love this Snow White costume, because it's cute and work-appropriate. The apple accessories and big red bow ($18, Kate Spade) complete the look.

If you work in publishing, this Anna Wintour costume is almost required. Wintour is coming, y'all — grab your bob wig, and the latest issue of Vogue.
6. Uma Thurman in Pulp Fiction
The good news? You probably already have these items in your closet. Just grab a short black wig with bangs, and you're good to go.

Get your resting bitch face ready, because on Wednesdays, we wear black. This outfit nails the original goth girl look.

Ugh. I want to forget "The Dress" was even a thing, but there's no denying it was a HUGE moment this year. Pair this pre-made costume with a sharp blazer, and you're good to go.
13. Elle Woods
This look is definitely not for those who shy away from pink. Carry around a law book, and/or a stuffed dog for extra credit.
