I don't really have a theme. This year I just by chance ended up with half black/white bindings, boots, and gloves. I've always worn black pants and have a black/white jacket (check my avatar).
I also picked up a green/black Oakley jacket that doesn't match my boots, bindings, or gloves, but I can care less. Sick jacket
I'm thinking of going with neon green pants though for that jacket.
