There might be more than two months until Halloween, but that didn't stop Kim and Kourtney Kardashian getting their goth on yesterday.

Dressing up in vampy PVC outfits that showed off a massive amount of cleavage (particularly Kim), they also went for matching dark lipstick and dark wigs with bangs.

She captioned the snap: "Banger sisters."

But the famous siblings were not going out trick or treating, sadly.

Instead the costumes were all in aid of a photoshoot with photographer Steven Gomillion.

And in case you were concerned that you couldn't quite see enough of Kim's chesticles in the snap, she later followed it up with an even-more revealing close up of her own boobs.

The pic appears to have been in aid of her passing 42 million followers on Instagram.

There's a woman who knows how to keep her fans happy.
