Marisa Miller, 'Sports Illustrated' And 'Maxim' Cover Girl, Has Worn Some Very Revealing Outfits (PHOTOS)

Although she is best known for being a Victoria's Secret Angel, landing the cover of the Sports Illustrated Swimsuit issue in 2008 and ranking #1 on Maxim's "Hot 100" list the same year, model Marisa Miller actually has a high fashion past.

The California-born model, who once placed second in the celebrity division of the Kelly Slater Surf Invitational, got her start in the industry when fashion photographer Mario Testino shot her for an editorial for Vogue in 2001. In the past decade, however, Miller has opted out of the high-fashion world for a sexier, more commercial image that better matches her athletic, surfer-girl roots. Her active lifestyle is reflected in her collaborations and endorsements: She teamed up with skateboard/surfer shoe company Vans in 2008, was a spokesperson for the NFL in 2010 and designed a line of paddleboards for women in 2010. Now that Miller has confirmed that she is pregnant with her first child, can we expect a line of stylish maternity-wear to follow?

To celebrate the model and mom-to-be's 34th birthday on August 6th, we're taking a look back at how her sporty style has evolved over the years. Which look is your favorite?
