Blue sweater over white shirt, brown knickers or short pants, white socks, tan shoes, and possibly a white wire fox terrier.

This kid pulled it off fairly well.
Or something more formal:
Yellow v-neck instead of blue sweater, black tie, matching brown jacket, and rockin' the black socks.
I think I'd need to color my hair, but a bit less drastically than I did last year. As for the little cowlick/tuft thing in front, I dunno ... maybe if I absolutely flatten the rest of my hair, I might be able to pull it off.
... perhaps that was a bad expression to use. "Get away with it," maybe.
