Sea's straightforward, on-trend appeal (and attainable price points) has definite sea legs. For proof, look no further than the New York label's through-the-roof sales. After an impressive Resort lineup that hit all the right notes, Sea picked up—count them—35 new stores in Europe alone. Designers Sean Monahan and Monica Paolini are keeping that momentum going with their latest Spring collection, which was inspired by a weekend trip the two took to Montauk this summer. You could see the sun and surf influence in long board shorts (albeit in tweed), variations of which have been all over this season, as well as in a printed canvas baja top. Monahan and Paolini also introduced denim into the mix for the first time with distressed selvedge pieces, including a chambray biker jacket with zip-off leather sleeves and red-dyed, slightly frayed cutoffs. It's easy to imagine the cool girls who hang out at Montauk hot spots like Surf Lodge and Ruschmeyer's wearing these clothes, plus other standouts here (like a batik lace patterned silk varsity jacket with hand-crocheted trim, which Barneys reportedly scooped right up), when they want to look cool without too much effort.
