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.
