Paper-shred chic, an oversized see-through shirt and crazy cutouts -- stars are rocking all the wrong trends this week!

Julianne Moore walked the red carpet at the "Maps To The Stars" premiere at the Cannes Film Festival, rocking a lamé organza Chanel gown featuring white pearls, sequins and white feathers. But, doesn't it just look like a dress made of paper shavings!?

Yes, that icy color is gorgeous on the actress, but whatever is going on around the crotch area is incredibly awkward. It's like an extra band of mini-skirt under the sheer dress!

Naya Rivera raised some eyebrows at the "Get Schooled" event to recognize student success at Collins Family High School. The "Glee" star looked like she was missing a tux jacket, conductor's baton and pants.

The blousy white look over those black mini shorts is unique, but the see-through top is way too big on the singer's tiny frame. 

And, Sharon Stone turned heads at amfAR's 21st Cinema Against AIDS Gala in France, donning a ruby-colored Roberto Cavalli gown with cutouts along her midsection. (It's actually a belt with nude mesh panels -- which strangely covers her belly button!) 

But these ladies weren't alone -- see more of this week's worst dressed stars in the gallery above.
