Is this even a contest? We admit it is not. The dress (once and forever known simply as That Dress) fits Liz better across the body, it’s the right length for her, her hair colour works better with it , the accessories pick up the gold and echo the shapes of the pins, and she has more sense than to wear a revealing drop dead dress with shoes that look like she mugged a fetish Clydesdale for them.
Also: face the same colour as body. These things matter when there’s that much skin on show.
Liz Hurley is fierce. Lady Gaga is forced.
