At a dinner at Kirsty’s, the tabletop resembles a garden. Serving dishes and plates are a fun jumble of different floral patterns. “I don’t like anything too formal,” she says. “That’s why I like mismatched things.” The secondhand silverware looks like family heirlooms. What unifies the flea-market-chic aesthetic are Kirsty’s collection of blue vases placed around the room, and plaid throw blankets.
