Twinning combo: For their 2008 Elizabeth and James launch at Selfridges, Mary-Kate and Ashley proved the power of black leather.  Mary-Kate wore a draping watercolor Elizabeth and James top over black shorts, then finished her casual look with an oversize blazer and over-the-knee leather boots. Ashley turned up the heat in a corseted top, black leather pants, and geometric Manolo Blahnik pumps.
