For designer Stephanie Hirsch and partner Stacy Josloff, bikinis and cover-ups aren’t just for summer—they’re year-round essentials. Their inca store (976 Lexington Ave., nr. 70th St.; 212-327-3007) provides one-stop shopping for winter despairers looking to ditch New York for Miami or Tulum. (Conveniently, the 700-square-foot boutique is about two blocks away from fellow resortwear shop Heidi Klein.) If your style is more glamorous sexpot than Nantucket conservative, swing by for plush, embroidered beach towels ($100), bohemian-chic throw pillows ($150), and gorgeous, club-ready silk caftans ($185 to $390). If you’re not finding a good fit for one of the triangle tops, or the bikini waist ties are too long, the made-to-measure program will customize any piece (from $250; up to four weeks for delivery).
A branch of Zonehampton, the East Hampton spinning studio, opens on January 17 (201 E. 67th St., at Third Ave.; 212-327-2170).
