By turns witty, sardonic, and always insightful, O’Brien’s advice column has been a must-read for several generations of men (and women). Most recently known as “The Style Guy” at GQ magazine, O’Brien dispenses well-honed knowledge on matters ranging from how to throw a cocktail party, putting together a wardrobe for a trip to Bermuda, or when it is appropriate to wear flip-flops in public (never).
