Marchesa Casati, the Italian heiress and early 20th-century patron of the arts, informed much of Kimora Lee Simmons’ fall collection. “To me, she represents unconventional beauty, edge, elegance,” Simmons said backstage. On stage, bits of Casati came through via the vintage-inspired Twenties silhouettes, floral fil coupes and in a velvet smoking coat with a feather detail. But there was also a Japanese influence evident, which Simmons channeled most successfully with an organza floral wrap dress with lantern sleeves and two kimonos, one a floral-embroidered version, the other a laser-cut gold and black one. On a more refreshing, modern note, she also offered a lineup of flatteringly cut jumpsuits and fit-and-flare dresses.
