Advertising costumes: original but funny to about 3 people

Bypassing the gory and the outright slutty, I like to choose costumes that have some personal meaning to me. So this year, I've dressed as Mary Wells Lawrence. No, not the go-go, ground-breaking Pucci girl of the 60s -- too obvious! too much leg! -- but the Mustique-residing, Mick-Jagger-cup-of-sugar-borrowing, legend-preserving grand dame of today. Several dozen colleagues have agreed to go as my personal servants, we'll pass out "A Big Life In Advertising" (stacks of which were rescued from the Borders bargain books shelf) and, when there's a spare minute or so, I'll patiently explain to anyone who will listen how I'm still emotionally in touch with the regular consumer.
