Mens Khaki Pants: Celebrities Wearing Khaki Pants. Superstar Brad Pitt goes around town in an all-khaki outfit: khaki slacks, khaki jacket, and a khaki-colored pair of shoes! We shouldn’t be surprised if it turns out that he’s wearing khaki-colored underwear, eh? By the by, it seems like our Brad is really loving him his unsightly beard, no? It’s been months since he looked clean-shaven so it seems like the beard is going to be for keeps. If he gains 150 pounds, he’s gonna be a good fit for a Santa Claus role.
