Concierge.com's insider take:
Former Calypso designer Joelle Klein has catered to denizens of the new Montauk with her sustainability-oriented beach shop since 2008. Sourced from all over the world, her offerings include Lostmarc'h fragrances and distressed sailor-stripe tops from Klein's native France, traditional Tunisian hammam towels, and espadrilles from Spain. Many items, such as recycled-paper ballerina flats and T-shirts made from old petticoats, come with fascinating backstories and are the sort of things you want to wear right out of the shop. Klein also sells coffee-table books on everything from architecture to surfing, and devotes the adjacent space to a different emerging label each summer.—Darrell Hartman
