White Rabbit Costume?

[hmerritt]

My daughter who just turned 3 has changed her mind 3x about what she wants to be for Halloween. My kids are insane and talk about Halloween year round, it's never ending. Anyway, we've gone from being a Princess to being a butterfly to now being the White Rabbit from Alice in Wonderland. And she's firm on this. Any suggestions, I'm sure there is no costume specifically for him, or might there be?

Thanks,
Heather
