Seating snafus at Rick Owens on Thursday — including plenty of double-booked seats — had editors scrambling for the front row like a game of musical chairs. It ended with the likes of Vogue’s Virginia Smith and W’s Treena Lombardo, among others, in standing room. Adrien Grenier merited the last row and Canadian artist Terence Koh was front and center in a fluffy white poncho. Koh said he’s preparing his first solo show at the Galerie Thaddaeus Ropac in Paris, which he described as an imaginary opera in two acts. It opens Tuesday. Next to Koh was Gareth Pugh, wearing an edgy ring from his latest collection.
