When I saw this Christian Dior gown on Amber Heard at the Third Annual Art Of Elysium "Heaven" Gala last month, it was love at first sight. Something about the mixture of textures (sheer netting, leather and satin), combined with the gown's overall retro-glam appeal screams modern Marilyn Monroe.

Suffice to say that when I spotted it on the red carpet for the second time (this time worn by Rosie Huntington at the Elle (UK) Style Awards), I fell all over again. While I'm still on the fence about who who wore it best, I'm beginning to lean toward Rosie's side.
