Sandra made an appearance at CinemaCon in Las Vegas last week to promote The Heat and opted for a rather graphic look from Roland Mouret. The actress wore the designer's black Bendals halter top featuring white accents and an open back partnered with coordinating Lomelo trousers. Gold bangles and a black pair of Rupert Sanderson Elba pumps served as accessories. We actually really like this crisp outfit on Sandra, but just wish the pants fit a bit better. Are you a fan of the star's black and white ensemble?
