Gwen Stefani's Fashion Evolution

Gwen was surfer chic at the beach when No Doubt performed at the Clean & Sober Beach Party on July 27, 1989. Her bandmates wore lime green and light blue trunks, while the No Doubt vocalist jumped into the water in a blue and white stripped bikini top, bold printed shorts and hot beach body.

Taking fashion inspiration from Madonna, Stefani took the stage at the Roxy on Sept. 12, 1989 in a white tutu, layered over a pair of heart-patterened bicycle shorts. She topped the look off with a thick pink belt, white hairbow and stripped socks that looked ready for trick-or-treat.

Gwen's retro-punk wardrobe began to take shape here as she performed at the Shoreline Amphitheatre on June 14, 1996 in yellow patent leather pants -- accented by black zippers and a chunky black belt -- and a cropped white tank top.

In December of 1996, Gwen rocked a long blonde bob for a party to celebrate No Doubt's "Tragic Kindgom" album. Her sheer red tank top left little to the imagination, and she accented it with a red pout, red nails, simple jeans and henna tattoos.

The No Doubt singer's outfit at the 1997 American Music Awards crossed a traditional Hindu adornment with a bird of paradise. Her classic Hollywood curls, black gown draped in dark feathers, and Bindi looked gorgeous, but what's with the platform flip flops, Gwen?

Before Katy Perry revealed her blue locks, Stefani popularized the electric-blue hair trend back in Sept. 1998 at the MTV Video Music Awards. While the hair is fabulous, the shiny, futuristic skirt-over-pants look is a little drab, and she could have done without the furry blue bikini top and alien-esque face decorations. We feel bad for the Smurf that had to die for this look!

With a hint of blue tint still in her hair, Gwen looked a bit out of place at the 1999 "Go" premiere in L.A. The oversized black jacket and shapeless pants did nothing to show off Stefani's fantastic figure.

Gwen's blue period came to an explosive end as she switched out the cool hue for hot pink locks. She showed off the look -- dressed in a black-and-white top and tight red jeans -- alongside her band on March 11, 2000 at MTV's "Total Request Live."

Gwen traded in her usual punk look for a sexy sailor costume at the 2000 My VH1 Music Awards on Nov. 30, 2000. The bright blue top is cute and fits her perfectly, the anchor belt buckle is a nice touch, but the sailor hat is a little over-the-top. And don't even get us started on the intense (some might say clown-ish) makeup.

We see a starlet in the making! Although this look (for the 2001 Grammys) is more glamorous than her previous red carpet ensembles, Gwen's structured, ankle-length red dress could have down without the sheer red gloves, fishnet stockings and too-casual white bag.

Gwen rocked Rapunzel-like pigtails and a little black dress backstage at the MTV Movie Awards in June 2001. The dress fits perfectly and looks chic with just a few subtle accents, but we miss Gwen's short curls! As usual, she wrapped it all together with a red lip and bright red nails.

Channeling the same surfer look she rocked in '89, the No Doubt vocalist showed off her envy-inducing abs in a little red bikini at the Teen Choice Awards on August 12, 2001. She went Americana with stars on her top and a blue starred belt holding up her white-washed jeans.

Although she changed outfits during the 2011 My VH1 Music Awards, Gwen kept the same theme, with red, Rastafarian and herringbone accents on both looks.

Part Avril Lavigne and part Irish step dancer, Gwen tried out a plaid punk look at the 2002 Super Bowl, with knee-high black boots, a single red biker glove, and a strange tie/bikini/tank top/vest combo.

Looking at Gwen's simple yet edgy look backstage at the 2002 MTV Video Music Awards, we couldn't help but wonder: who put Gwen's leather pants through the shredder?

Gwen Stefani married Gavin Rossdale on Sept. 14, 2002, looking like a fairytale punk princess in a billowing white and pink wedding gown custom-made by John Galliano. Gwen later donated her gown to the Victoria and Albert museum, saying the dress was a work of art.

Four months into her marriage, Gwen took to the stage at the Super Bowl on Jan. 26, 2003. Looking sporty chic, the singer rocked a glittering halter top with high-top Adidas kicks, black athletic pants and lacy red lingerie.

Going solo at the 2003 Grammy Awards, Gwen looked salaciously nerdy in thigh-high leather boots, camo short shorts, suspenders and a black bandeau with the wors "love" printed across the front.

Wearing an eccentric, Rastafarian-colored Dior creation and chunky red pumps, Gwen arrived at Dior's Dance for Life event on August 3, 2003.

Gwen hit a fashion hurdle at a Glamour magazine event on Sept. 7, 2003 in this horrible '90s-inspired look. The baggy jeans, leopard shirt and fur jacket were more throwback than fashion-forward.

Gwen returned to her old Hollywood curls and showed off her abs in an upward plunging white shirt and matching pants. As always, she wore red accents, and she paired the look with a L.A.M.B. bag as she revealed her line's collection for LeSportsac on Sept. 8, 2003.

The singer showed off her body again at the 18th Annual American Cinematheque Awards in a black plunging neckline dress and bouncy, 1920s-inspired blonde ringlets. She completed the flapper-esque look with an assortment of long, beaded necklaces.

Gwen channeled the bride of Frankenstein at the 2003 Billboard Music Awards in a structured, chambray suit with experimental stitching down the back, spiked heels and aggressively high hair.

Stepping out onto the red carpet in a delicate white Valentino gown, Gwen stunned at the 2004 Golden Globe Awards. While her pulled-back hair looked simple and chic, the fringed purse was a bit of a misstep.

Gwen sported a frilly and vivacious couture Chanel number to the 2004 Vanity Fair Oscar Party. The dress is glamorous and fun, but the fur shawl and bright gold clutch are a little too much.

The "Sweet Escape" singer looked a bit disheveled in this deep purple dress and Vivienne Westwood boots at a pre-VMA Party on Aug. 14, 2004. While we love Westwood's designs, these boots just don't work with this delicate silk dress.

Old world glam is exemplified here as Gwen walked the red carpet at the 2004 MTV Video Music Awards. With her light blue bustier top, form-fitting red skirt and the bold red flower in her hair, Gwen perfectly mixed vibrant colors.

Gwen walked the red carpet alongside her entourage of Harajuku girls at the 2004 American Music Awards, channelling Japanese style in a short, frilled skirt, white tights, top hat and ribbon-laced lavender pumps. The Harajuku girls, meanwhile, all matched in black tops, pink plaid cropped jackets, knee-high socks and different pairs of kicks.

Gwen looked pretty in pink and brought a classic glamour to the carpet at the "Aviator" premiere on Dec. 1, 2004. In a ruffled pink dress and big, loose curls, the singer added her own flair to the retro look with leopard-print pumps that peeked out from under her dress.

Stefani channeled the '20s once again at the 2005 Grammy Awards, where she walked alongside husband Gavin Rossdale in pearls and a sheer black dress that showed off her shoulders and her legs. Her hair was high, her lips were red, and her simple shoes let the Versace dress speak for itself.

Looking shinny and shabby, Gwen stepped out in a draped, over-sized, shiny champagne gown to a Fashion Week book launch party on March 2, 2005.

The "Hollaback Girl" has always been edgy, but over the years, her punk style has evolved. At the 2005 Festival of the Song of Saint Remo, Gwen took the stage in an open military jacket, small black gloves, and black-and-white blocked tights with a big red bow belt. Her animal print heels and pulled-back hair style wrapped up the sporty-but-sexy look.

Gwen quickly began creating a phenomenon in women's fashion with her Harajuku look, which continued at Movieline's Young Hollywood Awards on May 1, 2005. Gwen looked girlie and sharp in this refined plaid look, jazzed up with leopard heels, white leggings and an oversized camel bag.

Gwen kept it casual -- maybe a little too casual -- in baggy white shorts, a sleeveless printed T-shirt, gold bikini top and bandana headband at the 2005 Teen Choice Awards. For once, husband Gavin Rossdale was looking more put-together than his stylish wife.

Looking sexy and vivacious, Gwen stunned in this figure-hugging leopard dress at the 2005 MTV Video Music Awards.

Taking style inspiration from starlets like Marilyn Monroe, Gwen revealed her inner bombshell as she performed at Conde Nast's 2005 Fashion Rocks show in a glittering white dress and retro hair.

The playful Harajuku look returned as Gwen previewed her Harajuku Lovers apparel line in L.A. on Oct. 22, 2005. She paired her petite blue and white dress -- accented by bows and ruffles, inspired by "Alice in Wonderland" -- with bouncy blonde curls and red lipstick, of course. While her look was feminine and childish, her accompanying Harajuku girls were more sporty.

Once again wearing Vivienne Westwood boots, we were glad to see they actually worked with the ensemble this time! Gwen launched her L.A.M.B. men's sneaker collection at Barneys in a masculine, army green look and pompadour hair. The "Rich Girl" singer added a hint of feminine flair with her signature red lipstick.

Gwen looked bohemian and beautiful in a simple, short white dress at the 2005 Billboard Music Awards -- where the solo star was nominated for three awards. She added color to the simple dress with bright red roses woven into her multicolored floral crown.

Gwen's baby bump was starting to show at the 2006 Grammy Awards, where she rocked a leopard dress, which trailed into a dark green train, and a pregnant glow.

The fearless songstress sported a 70s-inspired wig -- straight and blonde with full bangs -- at the 2006 American Music Awards. Her whole look screamed "1970s spy," with aviators, a short white romper, blinged belt buckle and heavy gold pendant.

Gwen Stefani visited MTV's "TRL" on Dec. 7, 2006 in a stylish-but-professional look, complete with leopard shorts, a little black sweater, a thin tie and pulled-back hair with curled bangs.

Gwen's love for all things leopard continued as she strutted down the streets of New York City in December 2006, wearing a leopard trench and classy black heels, holding her latest accessory -- newborn son Kingston.

Dressed to impress, Gwen looked like she stepped out of a classic fairytale as she arrived alongside hubby Gavin Rossdale at the Vanity Fair Oscar Party on Feb. 25, 2007. Stefani rocked a layered, black and white chiffon Chanel couture dress and black Christian Louboutin pumps.

Continuing the black and white trend, Stefani sported a modern mod look in this short, houndstooth-printed dress and simple black pumps at her InStyle cover party on Sept. 5, 2007.

Stefani performed during the 2007 "Sweet Escape" tour in this striped, glittering black and white corset -- paired with a black tie, slouchy leather gloves and red lips, of course!

Gwen looked sultry and sophisticated as she arrived at in a toga-inspired, draped navy dress with diamond accents and black accessories at Conde Nast's Black Ball concert for Keep a Child Alive on Oct. 25, 2007.

Gwen and Gavin both looked dapper at Madonna and Gucci's 2008 benefit for Unicef. She walked the red carpet in a floor-length black gown with an orange and blue embellished neckline.

Gwen's casual look at Jane Goodall's 2008 Day of Peace wouldn't be a total disaster if the singer lost the white pants and rocked the yellow sundress with a cool pair of red sandals. There's something about flip-flops that just looks untidy.

Back on starlet track, Gwen looked phenomenal in this black tulle Chanel haute couture number and sultry red lips at the 2009 Vanity Fair Oscar Party. Wowza!

Stefani showed us she can do a casual look in a chic way at day in Palm Springs on March 11, 2009. The leather jacket, black trousers, and mustard shoes look badass and effortless on the singer.

Reunited with her band and rocking her retro twisted bun hairstyle from the '90s, Gwen performed on tour and on NBC's "Today" in black and white looks, mixing in chains, chunky boots, and bleach-stained jeans.

Rocking her namesake designs, Stefani posed backstage before the L.A.M.B Fashion Presentation in 2009. Her hair is poofed higher than ever, and we love the bright accents -- turquoise eyeliner and a bright pink bag -- that Gwen paired with her structured, pale blue jacket.

Gwen poses with her No Doubt bandmates, looking casual in a disheveled top, cloud-printed leggings, and a pair of pointed white pumps at the F1 Rocks Singapore concert on Sept. 25, 2009.

Returning to her classic black and white look, Stefani rocked a white corset, detailed with black lace embellishments and paired with bold, strappy black heels at the L.A. Museum Of Contemporary Art anniversary party on Nov. 14, 2009.

Gwen kept is simple in this all-black look at the Launch Party For HUE on Nov. 18, 2009. We love the statement heels and hint of color visible as her vibrant blue bra peeks out from under her top!

Looking like a melted Tin Man, Gwen arrived at a Beverly Hills party on April 15, 2010 in a disgruntled silver dress, unnecessary white tights and strappy black heels. Her hair and makeup looks gorgeous, however!

Our favorite look in Gwen's fashion evolution, the No Doubt singer stunned in this dramatic, sheer silk, silver L.A.M.B. gown that revealed just a hint of black lingerie at the Metropolitan Museum of Art Gala on May 3, 2010. This 1930s-esque dress is a lovely blend of boudoir inspirations and classic couture.

Gwen couldn't pick one color to wear during 2010 New York Fashion Week, so she wore them all. In one outfit, no less! We love the '70s color combination, but the mis of prints is just too much to handle.

The "Hollaback Girl" arrived to unveil her wax figure at Madame Tussauds on Sept. 22, 2010, looking darling in a short, geometric halter dress and black stockings.

Looking like the queen of the jungle, Gwen attended her L.A.M.B. fall 2011 show at NYFW in a leopard jumper she designed herself. Meow!

Even when she's just walking down the street with her family, Stefani knows how to make a statement. Wearing a structured red blazer, long gray T-shirt, black leggings and rain boots, Stefani shows off her hot street style in May 2011 with husband Gavin Rossdale and their kids, Kingston and Zuma.

Continuing to rock gorgeous street style, Gwen walks through London on May 10, 2011 in billowing jeans, a sheer black top, structured navy jacket and mirrored aviator shades.

During the Cannes Film Festival on May 16, 2011, Gwen stole the show in a glittering black sequined jumpsuit with a plunging neckline created by London designer Stella McCartney. She accessorized the ensemble with a new shade lipstick -- pink, not red! -- and hubby Gavin Rossdale.

Wearing a sparkling black L.A.M.B. dress with a silver belt, Stefani dazzled as she attended a party at the 2011 Cannes Film Festival. Again going without her classic red lips, Gwen sported a simple nude pout. This gal can do no beauty wrong!

Gwen stepped out in this lovely white and black Armani Prieve gown, lush red lips and a sultry smoky eye at the premiere "This Must Be The Place" at the 2011 Cannes Film Festival.

Looking proper but gorgeous, Stefani shows off her eclectic style in this patterned, fitted suit and bold gold necklace at the 2011 launch of her Harajuku Mini for Target collection in L.A.

The No Doubt singer looked like she rolled out of the house in her pajamas as she arrived to the "In the Land of Blood and Honey" premiere in Dec. 8, 2011 in a flimsy white jumper and black wedges.

Gwen looked striking in a mid-length lace Zuhair Murad Couture cocktail dress with rose details at the 20th Annual Elton John AIDS Foundation Academy Awards viewing party on Feb. 26, 2012 in West Hollywood. She accessorized the look with a pair of black pumps and a matching clutch.

This last ensemble is one of the best looks that Gwen has rocked over the years. She looked spectacular in this sensual, sheer black jumper by Stella McCartney and signature red lip at the world premiere of "My Valentine" on April 13, 2012 in L.A. It's feminine and flawless!
