We’ve come across many eye-popping fancy dress outfits in our time, but none quite as shocking as this.

Blac Chyna was showing off a lot (A LOT) of naked flesh at Amber Rose’s fancy dress birthday bash in Hollywood.

The barely-there outfit fortunately had a PVC panel running down the front and back, but it was no match for the, er, side-bottom.

Blac happily posed up a storm outside the Los Angeles venue, showing off her curvy figure and large tattoo on her right side.

Other guests in attendance included Chris Brown and his girlfriend Karrueche Tran, who was also wearing an outfit that left little to the imagination.

The pint-sized beauty was her usual vixen self, going as a very Sєxy bunny in a pair of over-the-knee lacy black boots and a wild leopard print leotard and a pair of bunny ears.

No, we’re not sure either. But somehow she manages to pull it off.

While Chris went as… Chris, it seems. The star failed to dress up for the party so it looks as though Karrueche put in all the hard work for the couple.

“Met some guy last night who was dressed as Chris Brown.. Cool costume bruh,” she tweeted along with the Instagram sH๏τ of the couple.
