What? Two sophisticated styles for two appearances on US television. First up was a slot on the Today show. Keira went for a daytime chic look in a black tee paired with a Christopher Kane floral embroidered pencil skirt and court shoes. This was followed by a quick change into something a bit more glamorous for the evening - a chain-embellished Little Black Dress by Valentino for Late Night With Jimmy Fallon.
Where? New York, 11 June
Verdict? Keira's pencil skirt has the potential to look a little frumpy, but she kept things simple by pairing it with plain black. As for her second look, who doesn't love a jazzed-up LBD?
