For the second year in a row, the New York-based interior designer Campion Platt will curate the Palm Beach Jewelry, Art & Antique Show’s Designer Showcase. Using fine art, furniture, and decorative accessories from the fair’s 160-plus international exhibitors, five of the country’s top tastemakers, including Platt, will create vignettes that demonstrate how to bring the past seamlessly into the 21st century, while championing the merits of fine art and modern design in contemporary interiors.
