Nicky Hilton's Master Bedroom
The fashion designer uses her L.A. bedroom for more than just sleeping. She often works on her laptop and hangs out with girlfriends when they visit. Hilton favors the tufted headboard in black patent leather, mirrored side tables, and Jonathan Adler ceramic accent pieces. "It's classic, but naughty," says Hilton. "The whole room has a cabaret feel."
