Billy Baldwin and Andy Spade are Katherine and Alexandra Yaphe's design muses.
Mid-century modern designer Billy Baldwin (left) was revered for his clean, pared-down aesthetic. "I love the personality of Baldwin's spaces. His style may be 60 years old, but it can still be pulled off today," insists Alexandra. Meanwhile, Andy Spade's Partners & Spade showroom (right), epitomizes quirky and cool design for the 21st century. Katherine admires Spade for "living the story — he started out copy writing, and now he has an art and accessories showroom in New York."
