For that sophisticated Halloween Dinner party you're throwing, wearing a full, complicated costume might make it difficult to entertain guests from the kitchen. Instead, slip into this slinky little silver minidress by YaYa Aflalo, throw on a pair of shimmery black tights and unless you live in my house (no shoes inside, please), black patent leather skyscraper stiletto heels. The black beaded spider on the racerback makes it perfectly subtle for Halloween.
