Kim and Khloe ensured all eyes were on them as the Kardashian/ Jenner clan arrived at the CFDA Awards in New York on Monday evening.
The reality stars joined forces on the red carpet as they posed together in their skin-tight dresses which showed off their shrinking curves.
Kim, 42, who previously called herself a 'shape shifter' after losing 21lbs earlier this year, showed off her slimmer frame in a strapless latex dress.
The racy gown featured a slit at the back and a corset bodice which enhanced her trim physique even more, with her famous derriere looking noticeably smaller in the number.
Khloe, 38, meanwhile, teased a glimpse of her toned abs in a gold floor length dress which had a cut out section on the midriff.
It comes after younger sisters Kendall and Kylie expressed concern for Khloe's weight loss, ringing Kim up to express their worry.
In an episode of The Kardashians which aired in September, Kim told Khloe: "You look very skinny, I will say that Kendall and Kylie, not that I’m trying to out them, but they did text me and say that they were a little concerned for you because you’re really skinny.
"I said, 'I think she’s a bit stressed'."
Kim then told Khloe she told Kendall and Kylie: "Guys, she’s fine'." I said, 'You absolutely have every right to be concerned, but I’m telling you she’s fine'."
Khloe later admitted in the confessional she was finding life hard after her split from her cheating ex boyfriend Tristan Thompson.
She said: "Going through what I went through with Tristan was incredibly hard. The hardest part about it all is training yourself to un-love someone.
"This was my life for six years and we weren’t just a couple, we genuinely were best friends. He was my workout buddy, we did all these things together."
And the sisters were out in force this evening as Kendall, 27, and Kylie, 25, also took to the red carpet.
Model Kendall looked ethereal in glamorous white dress while Kylie put on a daring display in a semi sheer gown with a racy thigh-high slit.
Matriarch Kris Jenner was also in attendance and hit the red carpet in a black gown.
The CFDA Awards, which held to celebrate the best of talent in the American fashion industry, had a star-studded attendance with Gigi Hadid, Irina Shayk and Cher hitting the red carpet.
