This is a style showdown we never thought we would see!
Rihanna shocked photographers when she stepped out in a completely sheer, green lace Gucci dress in New York City on Wednesday. The singer went braless, pairing the colorful frock with nothing but a pair of black briefs, chunky lace-up heels and metallic silver bag.
While we aren't surprised to see RiRi "freeing the nipple," we were stunned to see that Julia Roberts was the first celeb to sport this designer dress.
The actress wore it to the InStyle Awards back in October, but she covered up by adding a slip under the sheer style. She put her own spin on the design with a pair of black Gucci loafer pumps and black square glasses.
We don't love that red striped waistband on either star, so we're left undecided on this fashion face-off.
