Best Celebrity Style February 2012

This week, we were treated to an onslaught of pre-Academy Awards parties, premieres, and a few special occasions that drew out our favorite stars in high style. Jennifer Aniston was honored on the Walk of Fame and stepped out in fresh Chanel florals to celebrate, Jessica Chastain partied with her fellow nominees in a gorgeous emerald Elie Saab, and Amber Heard slipped into a sexy Antonio Berardi to fête Vanity Fair and Montblanc. Inside, there are more noteworthy fashion moments — some street-chic (we're looking at you, Rachel Zoe) and lots more straight from the red carpet. Click on to get a glimpse of all the standouts in this week's top 10.
