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. To entertain the evening’s guests, which included actress Olivia Wilde and Paul and Maurice Marciano, was 19-year-old pop sensation Kat DeLuna. Referring to her satin hot pants and sparkly bomber jacket, both by Marciano, Ms. DeLuna remarked, “My outfit is the most important thing, besides the vocals. “Movies Rock” will air this Friday at 9 p.m. EST on CBS.
