Kelly Wearstler has single-handedly revived the Hollywood Regency decorating style: a glamorous mix of bold lines and graphic patterns, rendered in luxurious materials and layered one upon another. Aside from creating eye-catching interiors for hotels, residences and restaurants — including BG, the eatery at New York’s Bergdorf Goodman — she has developed similar product lines for The Rug Company, textile manufacturer Lee Jofa and tabletop concern Pickard. But perhaps her crown jewel is her bedding for Sferra, which features zigzag stripes, color blocks and sinuous organic patterns in cashmere, sateen and embroidered ribbon.
