Amanda wore a layered statement necklace at the "Red Riding Hood" premiere in London. She wore a LBD and had her hair in waves; a touch of bright colour was added via her lipstick. I think it's a really bold look and works for the red carpet.
Emmy Rossum was at the Elie Tahari store, wearing a pleated lame gold skirt by the designer, pairing it with a tank top, matching gold necklace and suede heels.
