What to wear: Kate McKinnon's Weird Barbie is really just the doll whose kid had a little too much fun destroying her. Start with a babydoll-style hot pink dress with poofy sleeves (this Asos buy is perfect) and then go crazy. Hack away at a short blonde wig, grab some face paint, and draw a circle around one eye and some crazy, zig-zag lines across your forehead.
