Kardashian was also sporting diamonds, a thick dazzling choker, a matching triangle bra, and low-rise pants.
Kim showed the outfit as she recorded herself taking jello shots on the plane and later in the night on her party bus.
Kim also had sleek platinum blonde hair to finish off the icy birthday look.
But when the party made it to Vegas, the Kylie Cosmetics founder's private jet had to be turned because of intense wind storms, Kardashian explained.
"For the record... We did fly to Vegas and tried to land twice at two [different] airports. And it was too dangerous, so safety first always, and we flew home," Kardashian clarified in her Instagram story about trying to make it to the concert.
Still, she and her clan made the most of the situation when they arrived in Los Angeles as they decided to keep the festivities going at In-N-Out.
Kardashian's party guests included sister Khloé Kardashian, mom Kris Jenner, Malika Haqq, and her longtime family friend Stephanie Shepard.
Despite the squad missing out on Usher's Vegas concert, they still seemed pleased to chow down at the famous west coast fast food chain.
Kardashian's Instagram story further detailed that the group planned on filming for their Hulu series when they landed in Vegas.
She even shared that the show's crew still enjoyed the musical artist's concert, along with her close friend La La Anthony, who came in from New York to surprise her.
"So my bestie @lala flew in to Vegas from NYC to surprise me! That killed me. We didn't make it, and she was stuck in Vegas, but she still went [to the Usher concert]…" Kardashian wrote before adding that Anthony sent them vids all night.
"The FOMO was real. She had to rub it in," Kardashian added.
