Sheldon Cooper from The Big Bang Theory
Who doesn’t love the Big Bang Theory?! If you want a cosplay costume that also could double as everyday wear, you should definitely consider going as Sheldon Cooper. Websites like Think Geek sell the same shirts that he wears on the show, and your choice in pants is pretty big, including lame plaid pants like the ones pictured, and sometimes plain khakis. Pick your favorite Sheldon look and go nuts! It helps to have a severe haircut and to be painfully thin.
