In a true fashion-icon move, Chalamet wore actual sweatpants and sneakers to the biggest night in fashion — an especially daring move as he was one of the night's co-chairs.
According to GQ, Chalamet spread the love around wearing many of his favorite designers: A satin Haider Ackermann tuxedo jacket, a Rick Owens turtleneck, a few Cartier brooches attached to his sweatpants, and, of course Chuck Taylors.
"Whenever I visit America, I am always struck by the wonderful clash of uptown and downtown cultures, of music and sports, and all of this energy just mixing together," designer Ackermann told Vogue.
