Leave it to the nostalgic brass at Condé Nast Media Group to nudge Hollywood, if only for a night, back to its Golden-Age heyday. On Thursday evening, to celebrate the publishing powerhouse’s “Movies Rock” TV special, clothing label Guess hosted a party at St. Vibiana’s Cathedral in L.A. For the event, models were adorned in red and black boas and six outfits from the brand’s Marciano line, reports WWD.

"Movies Rock" will air this Friday at 9 p.m. EST on CBS.
