She's the all-American girl with her blond locks and girl-next-door charm. Since her breakout role in 2002's Blue Crush, Kate Bosworth  has become a style star on and off the red carpet. We're celebrating her 31st birthday with a look back at her standout beauty moments. It's clear she's made of star quality.
There was a new girl on the block back in 2002, when Kate hit the Blue Crush red carpet. Her baring cutout dress was a cue that she'd be one to watch for major fashion moments. She kept her makeup light and fresh to balance the drama of her dress.
Arriving at the opening night of Beyond the Sea, Kate donned a plum gown that she coordinated with a purple smoky eye. She pulled back her blond hair and left curls out to frame her face.
Long before orange was the hot shade of 2012, Kate showed off a tangerine ensemble at the 2005 Vanity Fair Oscar Party. The shades of orange on her eyes, lips, and cheeks really made the blue in her eyes pop.
Kate stepped out at the 2006 Superman Returns premiere in London with a radiant platinum blond mane. She kept her makeup simple with a little pink on her lips and a healthy dose of mascara, so her new hair color could be the center of the spotlight.
Making the Cut
Later in 2006, Kate was spotted at New York Fashion Week with a freshly chopped bob.
Kate worked the fashionable red carpet at the 2007 Met Gala in a flapper-inspired Prada  dress, which she complemented with a 1920s hair style and crimson lip.
At a dinner hosted by Chanel in 2010, the style star paired her floral and striped print dress with a sleek and sophisticated topknot, long before it was a major Hollywood hair trend.
The Burberry  Body launch in 2011 was all about fragrance, but we couldn't keep our eyes off Kate's lust-worthy hair. She perfected the naturally tousled look, from the slight wave in her hair to the imperfect middle part.
At the Life Happens premiere in 2012, Kate showed off a girlie way to add some edge to a beauty look. She went for a deep side part in her pretty waves and added a pop of hot pink on her lips.
Feminine and Polished
Attending shows at New York Fashion Week, Kate went for a pretty and polished look with loosely pulled-back hair and lots of pink blush and a pink lip stain.
Sleek and Modern
Kate arrived at the 2012 Target + Neiman Marcus  Holiday Collection last month in an ivory Emilio Pucci  dress, which she paired with a sleek long bob. She warmed up her Winter complexion with golden eye shadow, peachy blush, and a soft red lip.
At the Vanity Fair Oscar party in 2013, Kate showed off a crown braid and purple lipstick combination we are dying to copy.
Kate Bosworth  may be the queen of casual, but at the Homefront premiere in 2013, she dressed up her side ponytail with a classic crimson lip.
