Reese Witherspoon opted for an adorable floral frock for the the "Water For Elephants" premiere on April 17 in NYC.

The newlywed -- who chose Monique Lhuillier for the big day -- wore a sleeveless white Jason Wu number from the Fall 2011 collection as she joined co-star Robert Pattinson on the red carpet. Gold strappy Christian Louboutin sandals were a perfect match with the black floral lace details on the dress.

Witherspoon showed off her 4-carat diamond engagement ring and paired the huge rock with, what else -- more sparklers! Drop earrings and a selection of bracelets made the look ultra glam.

The recent Vogue cover girl ditched her retro poytail and instead tied her hair back in an unkempt updo. Major white eye shadow along the inner eyes mixed with a navy blue smokey shadow made the actress' baby blues really pop.

Meanwhile, Witherspoon is about to launch a series of three new fragrances for Avon. And we know what you're thinking: another celebrity, another fragrance -- but this time, the actress claims, it's personal.
