Christmas may be the "most wonderful time of the year," but Halloween is the high holiday of sexy costumography. If you want to stand out from the legions of alluring nurses, librarians and teachers, take some inspiration from the most seductive subject of all: internet memes! Show off your switchblade skills with a slinky Crab with a Knife costume, rock some socks as a toothsome hipster Ariel or just melt hearts with a sultry Doge outfit. There's no meme too obscure, no reference too random that you can't add your own sexy spin to it. Except maybe Pepe the Frog.
