Pretty actress Selma Blair appears to have forgotten a huge golden rule in the wardrobe department. You don't wear white underwear under a black dress! As the flashbulbs caught her fashion faux pas, Selma appeared non the wiser that she had arrived in a see-through dress at the Chanel Fine Jewelry event in New York City. I just can't help wondering why her knickers look so close to her knees? Pictures: Janet Mayer
