“I think this is a collection about thinking,” Alber Elbaz mused after his show yesterday. Did he really think that oversized nameplate necklaces with the words hot, cool, happy, love, and help suggested deep thought? “Thinking” at Lanvin, as Elbaz explained, includes speculation about the future pope, the balancing act between business and fashion, and some Beyonce-type pronouncement about women changing the world. Help? A man as savvy as Alber should know better than to deliver such easy foder for parody. Or maybe something got lost in translation? Beyond the thoughtful accessories, Lanvin was run-of-the-atelier chic with a few editorial-worthy eccentricities, such as the moth embellished satin tops and the beetle print jumpsuit (cool). In more a self-aware clueless move (*I think*), Guillaume Henry channeled Cher and Dior do preppy at Carven. Candy colors were matched with mulled wine and cafe au lait brown and it all looked delectable. Alexander Wang started the day, of course, with his cautious debut at Balenciaga. Then followed Ann Demeulemeester, Barbara Bui, Balmain, Nina Ricci, and Christian Wijnants, each doing their thing. Here’s what we liked from the blockbuster Thursday.
