The art of casual dressing — Marc Jacobs has become a master of it lately, whether adopting pajamas and furs as his own personal uniform or building familiar comfort into a glamour statement for fall. Those principles were encapsulated in his divine resort collection, in which he wanted “to do something relaxed and laid-back,” said head women’s designer Joseph Carter. More so than in recent pre-collections, resort reflected the previous fall and spring offerings in its use of delicate lingerie effects — silk slipdresses (fall) and bra tops and hip-slung skirts (spring) — topped with gorgeous jackets. The latter came waist-length and cropped in shades of brown and burgundy sequins with softly undone tie necks. Nautical provided another key motif — Breton stripes and sailor garb — cleverly reimagined as rabbit-fur tops and coats in blue and white. On the sportier side, simple, precisely cut slips featured horizontal panels of double-face satin with rhinestone-trimmed straps for a dose of unexpected femininity. Underscoring the overall relaxed nature, most looks were shown on variations of the shower sandal, here in satin pumped up with lug soles.
