2012: Our Family costume was Alice in Wonderland themed, with john as the Cheshire cat and Redding as the most precious white rabbit. You can see more family costumes here.
2011: The Big Bad Wolf and (a very pregnant) Little Red Riding Hood.
2011: For a zombie pub crawl we went as Zombie Andy Warhol and Edie Sedgwick
2009: My date and I went as 4 year olds (I was teaching preschool at the time, which was probably where the inspiration came from). I was a Princess-fairy-ballerina and he was a Cowboy-pirate-superman.
2012: Wicked Witch of the West (and yes, I totally rode my bike in those heels!)
2010: Sugar skull. (I also got all decked out in goofy outfits and wigs each night, which was super fun).
2010: Also, if you've just completely spaced on the costume thing, facepaint is always fast and easy!
Do you have old costumes favorites? I love looking through old halloween photos, there is always so much fun had when in costume.
