In 2011, at just 25 years old, Olivier Rousteing was named the creative director of the storied couture house Balmain. Throughout his tenure, the French-born designer bolstered the brand’s menswear business, bringing his signature skinny pants, gilded hardware details, and pronounced double-breasted blazers onto the runways and, eventually, into the homes of rock legends, pop stars, and any man that digs super-fitted cuts with a Parisian flair.
