Who Wore Stella McCartney Better? Stella McCartney or Liv Tyler

Stella McCartney designed this stunning cobalt blue one-shouldered gown, which she wore to the Costume Institute Gala in New York last month.

The gathered and slightly layered detail on the shoulder, really makes this dress stand out.

The designer opted for matching satin shoes and gold cuffs to accessorize her dress.

Liv Tyler attended the premiere of her movie The Incredible Hunk wearing the same dress, but a much shorter, sexier version.

The actress teamed her dress with a pair of black sandals.

I am not too crazy about Liv's shoe choice, and I think this dress works much better as a gown, so Stella wins this for me.
