Kim And Kourtney Kardashian Channel Their Inner Goths On Instagram


While Kylie Jenner was kicking off her 18th birthday festivities this weekend, Kim and Kourtney Kardashian had a "chill Saturday" which involved a little game of dress-up.

The "Keeping Up With The Kardashians" stars shared pictures of themselves in gothic-inspired ensembles on Instagram, and they looked practically identical.

Both Kim and Kourt donned dark, vampy lipstick, and Bettie Page-inspired hair, baby bangs and all. Kim wore a latex dress with a plunging neckline, while Kourtney opted for a strapless latex number with a crystal-embellished bra worn overtop.

Just a chill sister Saturday.

And Kim and Kourt weren't the only ones to go goth glam this weekend -- turns out all six of the Kardashian/Jenner ladies took part in a vampy photo shoot with photographer Steven Gomillion.

Khloe Kardashian rocked some seriously glam retro waves, while Kendall Jenner went more of the same route as Kim and Kourtney with baby bangs and dark lips. No word yet on what mama Kris or Kylie ended up wearing.

We can't wait to see how the shoot turns out!
