When Katy Mimari found herself pregnant and grappling with pastel overload, both her maternal and designer’s instincts kicked in. Beginning with just a half dozen diaper bags, she challenged traditional kiddie aesthetics with playful Moroccan prints, vintage paisleys, and colorful damasks. Before long, Mimari expanded into full-fledged nursery decor, with crib sets, toddler bedding, throw pillows, and accent fabrics. Clever accessories, such as age-designated closet dividers and tutu-shaped clip and beret holders, also factor prominently in the Caden Lane mix.
