By Alexandria Sage PARIS (Reuters) – Paris fashion week was a Lanvin love-fest this season as designer Alber Elbaz showcased a tassel-laden collection inspired by Morocco and kicked off a retrospective of France’s oldest surviving couture house. Lanvin’s Winter 2015 ready-to-wear show, which drew a newly blond Kim Kardashian to the front row on Thursday night, was a study in refined chic despite the liberal use of decadent velvets and satins and its pervasive Bohemian spirit. Also sporting platinum locks was actor Jared Leto, who added mirrored sunglasses and a pair of duck boots to the look for good measure. In an overdue homage to the house’s founder who died in 1946, the Palais Galliera fashion museum presents through August a retrospective of the work of Jeanne Lanvin, from golden pearl-encrusted turbans to airy silk dresses in shades of absinthe or sea-foam thickly embroidered with glittering crystals.
