She's gone from bubbly Mouseketeer grad to "dirrty," chaps-wearing diva, from '40s-style pinup queen to modern glamor goddess. But whatever look she rocks, Christina Aguilera never fails to turn heads with her eye-popping style. Take a look at 50 outfits that chronicle the "Voice" coach's fashion evolution over the past 13 years. Which garments hit the mark, and which ones missed the target entirely?

In 1999 Christina Aguilera went from The Mickey Mouse Club to stardom with her debut album Christina Aguilera. Nineteen years old, Christina walked the red carpet for the First Annual Teen Choice Awards wearing a multi-colored poncho and mesh skirt.

At the same event Christina reappeared as a sexy school-girl. Her belly-fetish and leopard prints become thematic for quite some years after, as well as her knack for switching-it-up mid-show.

Starting in 2000, Xtina started to diverge from the pop-teen look and experiment with her style. The success of her singles "Genie in a Bottle", "What a Girl Wants" and "Come on Over Baby (All I Want Is You) pushed her to a young-diva status. The doo-rag / crop-top combo was a popular re-occurrence.

At the 42nd Grammy's Christina received the award for Best New Artist. This gold-pants-and-halter piece was her outfit for the after-party, showing off Christina's love of bling and metallics. Her hair was tinged pink, foreshadowing a plunge into something vibrant.

At the MTV Video Awards, Xtina's hair went from pinkish to multicolored. She let a fair amount of skin show in this slinky, zebra sarong and bra. Too many gold trinkets accompanied this already painful outfit (is that a hanging gold belly chain?)

In 2001, after the success with her Spanish album Mi Reflejo, Xtina became known for her outlandish outfits thanks partically to the theatrics of her single Lady Marmalade (also featuring Mya, Pink and Lil' Kim). Her hair went from fiery to braided for this appearance at the 43rd Annual Grammy Awards. The thin, salmon crepe-dress is revealing but still fairly girlish.
Looking like she just undid the braid...
Looking like she just undid the braids, Christina goes all blond at the Blockbuster Awards. Her love of gold accouterments takes form in an oafish clutch, earrings, and a choker. Once again she sports pink crushed material with cutouts.

In addition to colorful clothes and corn-row hair, the Marmalade phase brought on colorful makeup, including Christina's iconic red lips.
Right before the release of Christina...
Right before the release of Christina's Stripped, her style transitioned into more skin with a sexier edge. This stylistic shift was controversial. This bumble-bee chaps piece combined with skunky hair and DIRRTY printed on her behind was quite a change from the whimsical cuteness of Lady Marmalade.
Continuing being DIRRTY, Xtina shows ...

Christina ushers in a generation of young women wearing this exact outfit- crop pants, stilettos and a page-boy hat. Slightly tom-boyish but mostly confused, she mixes a curled B&W 'do with fringed cotton and high-heels.

Sixteen days after Back to Basics debuted at #1, Christina wore this memorable gold-beaded dress on the red-carpet at the 2006 MTV Video Music Awards. The album, a throwback to 20's, 30's and 40's jazz, needed a refined starlet to catalyze the music.

After giving birth to Max Bratman, Christina comes back for her first in-store appearance signing Basics DVD sets. We always give a little leeway to the post-preggers for weight gain, but best not to over accentuate the change to the umpth degree. Xtina wears exactly the thing that she should not be wearing (i.e put those babies away).

Wearing something a tad more flattering, Xtina sports this Tori Amos/Elvira look at the 2008 MTV Video Music Awards. Returning to no-nonsense blond hair, it looks as if she might go minimal for a while.

Christina's most recent dip into a little black dress was simple as well as reminiscent of a winter-formal dress from the late 90's. Her modern and geometric hair chop is both flattering and mature.

Resembling a Taylor Momsen/Rihanna mashup, Christina strolled around the streets of New York looking wayyyy more sex-drugs-rock and roll than any of her former-selves. Black was never a color choice of Christina's, but it appears to be dominating this outfit.
