It's sheer madness!

Rihanna rocked a very revealing look for a casual dinner at Giorgio Baldi in Santa Monica, Calif. on Thursday night, sporting a completely sheer Simone Rocha white plastic skirt which put her hot-pink panties on display.

In addition to the revealing lace skirt, which cost a whopping $2,800, the "Diamonds" singer wore a cropped sweater and matching lace oxfords, trading in her new blunt bob for a Rapunzel-like pony tail. 

RiRi is no stranger to showing a lot of skin!

She created a fashion frenzy during Paris Fashion Week when she bared her nipples in a fishnet top -- with no bra -- at the Balmain fashion show after party.

We can't wait to see what the 26-year-old superstar wears next!
