The work compiled in Hagan's book, Interior Portraits, defines a thoroughly American sense of style—casual, honest, and optimistic. Her light-struck living rooms tempt you to put your loafers up and stay awhile. "I'm in the happiness business," she says. "I like my work to feel relaxed and natural."
From Malibu to Palm Beach, Hagan creates rooms that inhale coastal color and light. "The texture of the sand and the changing palette of the water are my inspiration," she says. "I try to connect that sense of water to the interior in subtle ways." —M.C.
