“One of the greatest aspects of Calypso is our customers are as passionate about the brand as we are,” says Calypso St. Barth President M. Oliver Regan, who rolls out a relaunch of the brand at Tenet in East Hampton and Southampton this summer. “As a brand, we have looked back at our heritage and have expanded in an elegant way,” he says. “We speak to the sophisticated woman who loves unique, timeless pieces.” Back are the fabrics we all know and love: cotton-silk voile, linen, poplin, silk chiff on and charmeuse—in the beach-inspired color palette of salty, sun-washed hues (think sandy neutrals, turquoise, lush greens, vibrant sunset pink and orange). Debbie Bancroft, previously Calypso St. Barth’s adviser and a loyal customer, says, “I am thrilled to see what I know is the essence of the best of Calypso St. Barth return at a time when we could all use a celebration.”Tenet, 21 Newtown Lane, East Hampton; 91 Main St., Southampton
