Katy Perry appeared to go completely nude underneath a geometric cut-out dress as she walked the star-studded runway at Vogue World Paris on Sunday evening.
The singer, 39, made a surprise appearance on the catwalk in the barely-there ensemble and joined a host of celebrities.
She flashed her cleavage in the racy look and covered the rest of her modesty with floral motifs.
The beauty opted for a dramatic makeup look, a swipe of bold pink blusher and lipstick.
Katy strutted around the famed Place Vendôme in front of star-studded guests, wearing towering tie-up heeled boots.
