The Many Styles Of Britney Spears, Ranked From Not To Hot

She's had some fantastic fashion dos... and some serious style don'ts.

20. Denim Britney, The 2001 American Music Awards

Sure, Justin Timberlake is an amazing accessory. But nothing can save this denim on denim combo. Levi Strauss is turning over in his grave.

19. Leather Police Officer Britney, The 2002 VMAs

Leather, lace, straps, gloves...and a police hat? Not your best, girl.

18. Bald Britney, 2007

The shaved head really doesn't do much for her features.

17. Bedazzled Lingerie Britney, The 2007 VMAs

While this is a fierce set of undergarments, Britney seems a little underdressed for a public appearance, literally.

16. Working Woman Britney, Womanizer

Pinstripes and glasses and bobs, oh my!

15. Pink Panties Britney, I'm a Slave 4 U

Last I checked, g-strings were meant to be worn under your pants, not over them.

14. Ring Leader Britney, Circus

Very intricate costume. But doesn't it feel like she's wearing a lot of clothing here, for her at least?

13. Flight Attendant Britney, Toxic

Gotta love a pillbox hat contrasted with a super peek-a-boo neckline.

12. Red Spandex Britney, Oops! I Did It Again

If anyone can pull off a bright red spandex catsuit, it's Britney.

11. Crop Top Britney, Crazy

Abs alert! The shiny emerald crop top is hot, but it's a little basic for Ms. Spears.

10. Wedding Dress Britney, The 2003 VMAs

So for Britney, this night was not so much about the outfit, but the look is somehow working for her, even if it is a little corpse bride meets house of ill repute.

9. Mouse Ears Britney, The Mickey Mouse Club

Decked out head to toe in Mickey Mouse gear, young Britney was as cute as ever.

8. Crystallized Britney, Toxic

Ok, she has a killer body. But in no universe does this outfit count as "clothing."

7. Baby Spice Britney, ...Baby One More Time Tour

Britney channels Emma Bunton with high pigtails, a pink pleather tracksuit and platform sneakers. But really, what's with the knee patches?

6. Cute Waitress Britney, Crazy

The pigtails, the glasses, the bedazzled B on her dress... Just adorable.

5. Sexy Waitress Britney, Womanizer

Badass sex appeal, and those blunt, burgundy bangs are really working for her.

4. Sparkly Britney, The 2000 VMAs

I mean, if this isn't the sexiest get up that has ever existed, than I don't know what is.

3. Baby Britney, ...Baby One More Time

Such innocence.

2. Sexy Snake Britney, I'm a Slave 4 U, The 2001 VMAs

She accessorized with a snake. A LIVE SNAKE.

1. School Girl Britney, ...Baby One More Time

But nothing can ever outdo Britney's first big "hit" -- the sexy school girl with the puffy pink pigtails will be her best look for all eternity.
