Despite the fact that his best disguise consists of only a baseball cap, Joe Goldberg continues to evade consequences for his actions on Netflix's "You." As Joe, you may not be able to blend in or avoid scrutiny as well as he can, but fortunately, a Joe costume is quite easy to put together. Just adopt a tweed jacket if you're going for his professor era from season four and grab an old book of some kind, and don't forget his signature cap.
