( -- What better way to wrap up 2012 than with a look back at the year's loveliest dresses?

Whether soft and sweet like Keira Knightley's pastel Erdem gown, a complete knockout like the Lanvin mini Emma Stone wore, or something in between like Catherine, Duchess of Cambridge's bold and romantic Jenny Packham stunner, these 10 red carpet picks have one thing in common: they're just plain stunning!

Rosie Huntington-Whiteley EVENT: The Art + Film Gala DESIGNER: Gucci WHY WE LOVE IT: Sexy can be pretty too! Especially when the dress is in a vibrant hue and accented with ruffles.

Jessica Chastain EVENT: "Madagascar 3's" Cannes premiere DESIGNER: Giorgio Armani WHY WE LOVE IT: The actress complemented her gown's Old Hollywood glam with side-swept curls and scarlet lips.

Emma Stone EVENT: The Met Gala DESIGNER: Lanvin WHY WE LOVE IT: She may have gone blond, but Stone was still red hot on the carpet in her crimson dress.

Biggest Hair Makeovers of 2012
