Last year: Tina wore a black-and-white floral dress by L'Wren Scott and pumps by Salvatore Ferragamo. Amy went with a tux by Stella McCartney and shoes by Charlotte Olympia.
This year: Tina wore a floor-length, patterned Carolina Herrera gown, and Amy sported a ladylike Stella McCartney evening dress.
Winner: 2014. Amy's tux was bold, but Tina's gown makes this year the clear winner.
