Literary Halloween Costumes

Do you know what you are going to be for Halloween? I've come across a few amusing literary Halloween costume ideas lately that I thought I would share with you. Why be a boring old ghost when you could be Miss Havisham, or Captain Underpants. They have some good ideas at Lit Drift. On the other hand, consider what famous literary characters would like to wear for a costume. Spark Life proposes that Holden Caulfield wouldn't dress up because it would be too phony, and Edmund from The Lion, the Witch and The Wardrobe would be a box of Turkish Delight. The most unexpected find were the pet costumes featured in the Critterati Contest. Waiting for Dogot cracks me up. Make sure to look at both slide shows on this page.
