Giambattista Valli’s ongoing affair with the Sixties and Seventies was in full flush for pre-fall. Colorful, nature-inspired prints — florals, cherry blossoms, bugs and mushrooms — infused his romantic looks with a cheerfulness. Valli loves a ruffle almost as much as he loves a retro reference, and his silk chiffon dresses and blouses, finished with gorgeous lace-embroidered cuffs, were full of frills. Yet he tempered all the frou with sportier pieces, such as metallic tweed jackets and sequined knitwear. Valli’s outerwear was superluxe and creative this season: A chevron, belted mink coat was chicly graphic, and an orange shaved shearling coat, cutout and embroidered to look like a patchwork of flowers, was remarkably constructed.
