PHOTOS: Rihanna stepped out in a completely see-through dress!

On Thursday night Rihanna took things to a whole new level as she arrived at Eden nightclub in Hollywood wearing a completely see-through dress.

The 24-year-old singer went bra-less for the night out, with the sheer fabric of her ensemble showing her skimpy black underwear beneath.

Rihanna let her incredible figure take centre stage with her outfit choice, keeping her make-up simple with just a slick of red lipstick, and wearing her hair down and to the side.

The Diamonds singer finished off the outfit with a pair of pink and gold toe-cap heels, complete with an ankle strap.
