Gwen Stefani Style Evolution: From Sporty No Doubt Singer To Glamorous L.A.M.B. Designer (PHOTOS)

This famous singer-turned-style icon once was just a girl in a (cute) bikini.

Gwen Stefani's hair has been just about every color in the book: blue, pink, blonde... the list just goes on and on. And her wardrobe has been just as vibrant.

When she first hit the music scene in 1986, the "Settle Down" singer was known for her sexy grunge aesthetic. While she maintained this style throughout the '90s, she slowly started to transform into a much more glamorous star. By the time she launched her clothing and accessories line L.A.M.B. in 2003, Stefani was a platinum blonde, favoring more minimalist and monochromatic ensembles on the red carpet. But now that she's reunited with her No Doubt bandmates, her stage costumes continue to showcase her signature abs and ska roots.

To celebrate Gwen Stefani's 43rd birthday on October 3rd, we're taking a look back at her greatest outfits. Which is your favorite?
