While the night will definitely boast some jaw-dropping looks, there's always a few stars who stun ... and not in a good way.
Florence Welch wore one memorable look to the 2013 award show -- the embellished spikes on the bright green dress are great ... if your going as a dinosaur for Halloween!
Rihanna definitely missed the mark in 2011, when she wore this fluffy white sheer ensemble. We know that RiRi likes to push the boundaries, but this dress is just a no-no. Really, who let the singer go out of the house wearing this outrageous outfit?!
While P!nk knows a thing or two about fashion now, the pop star clearly should have enlisted a stylist for the 2003 Grammy show! This dress looks like it has been dragged behind a car for miles, and the hair and makeup seem to make matters worse (if that's possible).
We can't wait to see what crazy couture the stars wear this year -- click "Launch Gallery" above to see the worst dressed stars from the Grammys' past!
