California Girl

Since her days as frontwoman of No Doubt, Gwen Stefani has accented everything she does with her own distinctive sense of style. And one of Gwen's most admired (and copied) looks is this one: sexy, tough and toned in a plaid slacks, a string bikini top and striking makeup. SoCal style has never looked so cool.

Bedazzled Babe

In 1997, two years after No Doubt's breakthrough album 'Tragic Kingdom' was released, Stefani developed an affinity for bright Indian prints and bindi face jewelry. Gwen stepped out in this sari skirt and showed why she was (begrudgingly) the face of alt-rock's hottest band.

Gwen's Blue Period

Stefani made a bold statement with her blue hair and matching bikini top at the 1998 MTV VMAs. The punky star looked Smurf-tastic and sent teenaged fans (dubbed "Gwennabes") to the hairdresser to update the hues of their own dos.

Rock's First Set of Grillz?

By 1999, Stefani's hair had gone from blue to fuchsia and she started sporting a dazzling smile, courtesy of her colorful braces. Her choice of hair color may have been inspired by her love life; it was around this time that Stefani started blushing over her soon-to-be husband Gavin Rossdale, formerly of rock band Bush.

Underneath It All

From punky pink to puttin' on the ritz! On the red carpet at the 2001 BET awards, Stefani embraced the platinum blonde locks and fire-engine red lipstick that would be her trademark for years to come. Meanwhile, the dapper starlet was starting to dabble in her own clothing collection, named 'L.A.M.B.'

Simple Kind of Life

In 2003, the newlywed continued her love affair with early twentieth century fashion. At that year's Billboard music awards, she walked the red carpet looking like a glamorous World War I entertainer.

One Hot Hollaback Girl

Stefani was impossible to miss in her green sailor pants and colorful top when she strutted her stuff at the 2004 premiere of the film 'Anchorman.' That same year, she made her film debut playing silver screen goddess (and fellow fan of platinum locks) Gene Harlow in 'The Aviator.'

If I Was a Rich Girl

Stefani embraced a vamped-up Alice in Wonderland look on the 2004 VMA catwalk -- a look she also sported in the video for 'What You Waiting For,' the debut video from her first solo album 'Love. Angel. Music. Baby.'

Animal Ambition

With her album producing a string of hits, Stefani choose to play the early '40s glamour girl in this sexy dress at the 2005 VMAs in Miami. No one does form-fitting leopard print better than this California girl.

Hey Baby!

In December of 2005, Stefani and Rossdale announced that they were expecting their first child. Not surprisingly, Stefani made pregnancy look sexy at that year's Billboard Music Awards. The Frida Kahlo-inspired hairpiece, used in her music video for 'Luxurious,' is set off by the starkness of her short white dress.

Cat Power

In her own L.A.M.B. creation, Stefani glowed on the red carpet at the 2006 Grammy Awards, where she was nominated for six awards. Although the mama-to-be went home empty handed, she's got other things on her mind -- like a branch of her clothing line for kids. The only question: Which of her many styles will she dress the tots in?
