Get ready for some crazy red carpet couture!

The 2013 Teen Choice Awards are tonight -- and what better way to kick off the show than taking a look back at some of the fashion disasters to hit the arrivals line.

Kristen Stewart has come a long ways since her 2009 metal red carpet look. They say beauty is pain, but this silver studded skirt looks like it could have caused some serious damage! Ouch.

Kelly Osbourne would have slammed her much younger self on E!'s "Fashion Police" for stepping out in this frumpy, goth number back in 2002. We're so glad her black spiky hair days are finally behind her.

And while Britney Spears still manages to make her 1999 pink sequined pants look adorable -- those things are blinding ... in more ways than one!

We can't wait to see the stars' red carpet hits and misses tonight -- make sure to come back to toofab for all the 2013 Teen Choice Awards red carpet coverage, and click "Launch Gallery" above to see the worst dressed stars of the Teen Choice Awards' past!
