East Hampton, NY : Lucky Magazine

Bellhaus

This 2008 arrival is way off East Hampton's main shopping drag, but it's worth seeking out for the range of items you're sometimes hard-pressed to find in New York City proper, like Pierre Hardy gladiator sandals, Vincent Longo lip glosses, and Tomas Maier bikinis.
328 Montauk Hwy. Wainscott, 631-537-5050

Blue & Cream

Jeff Goldstein's popular Hamptons boutique—which now has a sister shop in NYC's East Village—is split into two rooms. The first is all Hervé Léger dresses, super-soft Kain T-shirts, and Alexander Wang blazers; the other is theoretically for guys, though there are limited-edition Nike Dunks and Ksubi sunglasses that work for women, too.

Calypso Home

Ikat pillows, pounded silver serving platters, plus the house line of fragrances and candles are all excellent houseguest gift options—and all plentiful at Calypso Home's only Long Island outpost.
17 Newtown Ln., 631-324-8146

Catherine Malandrino

This French designer's easy elegance—chiffon dresses with delicately beaded collars, crisp white pants, and jewel-toned blouses—perfectly embodies the dress code for impromptu dinner parties and beach barbecues.

Coach

This recently revamped boutique is packed with a summer-centric mix of oversize sunglasses, straw totes, and silk scarves—in Coach's signature, hyper-bright shades.

Cynthia Rowley

Perhaps the ultimate destination for summery cocktail dresses—some are printed with picnic plaids, others are decorated with embroidery—this boutique oozes perfect Hamptons style.

Henry Lehr

These boutiques now blanket the East Coast—which makes perfect sense, since Henry Lehr was one of the first (way back in 1989) to display an entire wall of denim. The East Hampton branch offers much more than just jeans, like cashmere cardigans by Vince and slightly rumpled Golden Goose button-downs.

Intermix

One of America's most popular boutique chains, Intermix tailors its Hamptons mix with on-trend picks from designers like Diane von Furstenberg, Stella McCartney, and Elise Overland.

James Perse

All of James Perse's neutral-hued boutiques—from the one in the Malibu Country Mart to his Bleecker Street shop in New York City—subscribe to the same surf-shack aesthetic: weather-beaten wooden floors, lattice-like walls, and a scattering of surfboads. And, since the much-loved broken-in T-shirts are perfect for the beach, the East Hampton store has a particularly deep selection of them.

Jarlathdan

Before launching this exquisite home goods store in 2004, Jarlath Mellett was the design director for Theory. This in part explains his take on interiors: The store serves up clean-lined furniture and then a wonderfully over-the-top wash of accessories, like cerulean goblets and ceramic busts.
