Did Pharrell Williams Wear a Yarmulke at Chanel’s Métiers d’Art Show?

What did Pharrell Williams have on his head at the Chanel Métiers d’Art show in Paris on Tuesday? The musician walked the runway in a long dark blue version of Chanel’s signature tweed jacket, a black shirt, and matching jeans, with strings of Chanel pearls draped around his neck, silver gloves in (not on) his hand, white shoes, and a hat markedly smaller than the ones he typically wears.
