Even though scary clowns and superheroes remain some of the most popular costumes this year, there is one surefire Halloween outfit that is not only easy to assemble (all that’s needed is some khaki pants, a sensible polo and a mustache) but is truly a timeless modern classic: Ron Swanson.

The costume was such a hit that Ron himself—actor Nick Offerman—spotlighted some of his favorites on Twitter. 

You win Halloween again, Swanson.
