Show (Air Dates): Mork & Mindy (1978-1982)
Actor: Robin Williams

A definite precursor to Power Ranger fashion, Robin Williams' star-making performance as alien visitor Mork in Mork & Mindy proved that red-and-silver onesies and Rainbow Brite–like hues weren't just for kids. Or females. Worn by themselves, those loudly striped shirts, multicolored puffer vests, and rainbow suspenders (okay, maybe not the latter), wouldn't look half-bad today.
