Kristen Stewart rocked the fashion world on Thursday as she arrived in a see-through jumpsuit at the Zuhair Murad show during Paris Fashion Week.

And the former girlfriend of Twilight co-star Robert Pattinson  --who is now rumored to be dating Elvis'  granddaughter Riley Keough --wasn't shy about displaying her sexy style for delighted fans and photographers.

Stewart flashed her backside in her designer onesie, featuring a strapless black bodice top and sheer lace pants.  While she arrived in frumpy black flats, the star quickly ditched them for spiky- heeled Christian Louboutin shoes displaying the designer's signature red soles.
