Nerd Boyfriend is a Tumblr that provides a guide to dressing your significant other in the style of pretty much every male nerd superhero you can imagine—from Adam West to Woody Guthrie. (Plus quite a few dudes that I don't really think of as geeky icons, like Yves Saint Laurent. But maybe that just because my list of nerderies doesn't include "fashion".)
I'd be intrigued by this Carl Sagan cosplay ... that is, if my husband didn't already pretty much dress exactly like this.
