Long hailed as the summer playground for New Yorkers, the Hamptons spring to life each Memorial Day as throngs of visitors flock to the idyllic beach towns. But when you’ve had your fill of what Frommer’s calls “some of the most beautiful beaches in the world,” here are a handful of shops where you can escape the sun and get your retail fix. Laurin Copen Antiques | Bridgehampton Tucked into a charming, circa-1791 farmhouse, Laurin Copen’s antique store feels more like a cozy home than a shop. The former illustrator and furniture designer—and protégé of luxury furniture manufacturer Karl Springer—has a distinguished, eclectic taste; her store’s wares span decades and continents, though there’s an apparent focus on French, English, Swedish, and folk art. Whether you’re on the hunt for a 19th-century library chair, driftwood sculpture lamp, or tongue-in-cheek hand-painted sign, chances are you’ll find it here. Haute Hippie | East Hampton and Southampton Run by tastemaker Trish Wescoat Pound, a former president of Women’s Sales at Theory, Haute Hippie sports an inventory that ranges from floor-length evening gowns to breezy bathing suit cover-ups. This summer’s collection includes a spate of beaded tanks, floral sundresses, and embellished mini skirts. Though the boutique has a handful of New York City locations, the two Hamptons storefronts embody the laid-back but stylish lifestyle that characterizes the area. According to the website, the Haute Hippie customer is “eclectic, chic, and well-traveled,” which describes the Hamptons set quite well. It’s a favorite among the Hollywood elite, too—celebs including Jennifer Aniston, Heidi Klum, and Blake Lively have been photographed wearing the brand. Black Cat Books | Shelter Island This independent bookstore on Shelter Island has been buying and selling gently used books since 1996. Today, its inventory includes more than 20,000 titles, including vintage collectibles and rare, signed first-edition prints. Swing by to browse entire rooms dedicated to genres such as art and photography, architecture, or music and film. MONC XIII | Sag Harbor A Sag Harbor highlight since 2011, MONC XIII is a one-stop shop for all things homey: high-end furniture, lighting, kitchenware, rugs, and accessories. Owner Natasha Esch curates her merchandise with a skillful eye, her taste honed during the 12 years she spent as an interior designer in Los Angeles. The goods include midcentury-modern sofas, cozy throw pillows, flatware, and modern leather accessories. Even the exterior of MONC XIII is a visual treat: while Esch reworked and modernized the interior of her store, she left the historical exterior—a white clapboard building that dates back to 1890—untouched.
