Leave it to Marc Jacobs at Louis Vuitton to make something covetably collectible out of the resort season s most predictable clichés. Inspired by vintage travel posters—not to mention old forms of elite island-hopping—he whipped up everything from forties-style nipped-waist dresses to hippie deluxe caftans in cruise-ship and prop-plane prints, often tossing on an anchor-shaped brooch for good measure. On a less whimsical but no less cheery note, he revisited some of the painterly pastels he used for fall. One lilac satin skirt was topped by a lemon-yellow bow-front blouse and a raspberry pullover sweater. The standout evening look, though, was a simple black jersey number wrapped goddess-style and secured over one shoulder with giant gold links. Worn with flat lace-up sandals, there was nothing retro about it.
