The Royal Wedding was the most talked-about social event of the decade, with weeks of buzz surrounding who would design Kate Middleton's gorgeous gown.

At the 2011 Golden Globe Awards, Angelina Jolie dazzled in an emerald green Armani gown, while Olivia Wilde was the belle of the ball in a stunning strapless Marchesa creation.
The next month at the Academy Awards, Black Swan babe Mila Kunis looked lovely in her lavender lace Elie Saab gown.
Beyonce used the black carpet of the MTV Video Music Awards to reveal her very first baby bump in a bright orange Lanvin one-shoulder number.
Breakout style stars included Transformers: Dark of the Moon's Rosie Huntington-Whiteley and The Girl with the Dragon Tattoo's Rooney Mara, both of whom went on superior style streaks to promote their first major movie roles.
