Kanye left the shirt unbuttoned, pairing it with jeans from another French luxury brand -- Balmain -- and accessorizing with piles of gold chains. Simpson put a different spin on the look, which she wore to lunch with friends at Balthazar in NYC's Soho neighborhood, rocking glam oversize shades, distressed bell-bottoms from her namesake denim collection, and a smart brown leather satchel.
This isn't the first time Kanye's been seen sharing a unisex design with a female celeb. This winter, West and Liv Tyler wore the same Rottweiler sweater from Givenchy's fall 2011 menswear collection to the fashion house's Paris runway show. And yes, there's a Kanye lyric for that label as well (See "Looking for Trouble," in which he directs, "Take off that Givenchy and let's get raunchy").
