It's officially time to retire your flannels. Just ask First Lady Claire Underwood, played by Robin Wright on Netflix's House of Cards. We did a double take when she breezed into her White House bedroom in perfectly-tailored silk separates by La Perla. "I love that the classic menswear cut is softened by the silk fabric," says costume designer Kemal Harris. "Even though it's a relaxed silhouette, I still had to tailor the heck out of them to make sure they fit her perfectly." Another secret from the wardrobe department? "We had the same pair in black and white," explains Harris. "We switched between them for various scenes, depending on where Claire was emotionally in the storyline." You can scoop up a a set of your own for $398 in black, white, cream, navy, or peach.
