Khloe Kardashian Stuns in Skintight Latex Dress During Scott Disick's Vegas Birthday Party

Can you say 'revenge bod'?

Looking good, Khloe Kardashian!

The 31-year-old reality star hasn't exactly kept her workouts a secret, but that doesn't mean we weren't still shocked by the ah-may-zing ensemble she rocked at Scott Disick's birthday party in Las Vegas on Friday.

Khloe pulled out all the stops for the soiree at one of Scott's top hot spots, 1OAK inside The Mirage Hotel & Casino. She wore a skintight blush-hued House of CB latex dress, which she paired with gold-and-diamond jewelry and pointy subtly striped white pumps.

She added a smoky eye, matched her lip to the curve-hugging frock's hue -- which appears to be a favorite as of late -- and wore her blonde hair down in long, beachy waves.

Her BFF, Malika Haqq, and sister, Kourtney Kardashian, weren't slackers in the fashion department either, rocking a deep V-neck LBD with a thigh-high slit and green printed Versace mini, respectively.

Barbie glam is becoming Khloe's new thing, and we can't say we're upset about it! The Keeping Up With the Kardashians star took to Instagram on Saturday to reveal that the look took a bit of work, however. "My girls really work well in chaotic situations lol it was a crazy afternoon but they came through for me!" she wrote. "Thank you @jenatkinhair and @styledbyhrush for my Barbie Vegas glam!"

It was quite the departure from the outfits Khloe and Kourtney wore for Scott's first bash, which took place on Thursday, his actual 33rd birthday. The siblings turned the fête into a theme party with their quirky looks -- just please don't ask us what that theme was supposed to be.

The Kocktails With Khloe host has been working extremely hard on her fitness, detailing much of her health journey via social media. Not only is she frequently featured in Kourtney's Snapchat videos, which show off some insanely hard workouts that the sisters push each other through, she also takes her own selfies at the gym -- some of which have even caused a bit of Photoshop criticism.

In fact, it's tough to forget her progress shots, considering one of the most recent selfies showcased her flat abs and butt as she was laying in bed last month.

It's no surprise that with all that hard work, Khloe is quite proud of her new figure. Check out the see-through catsuit she rocked to Beyonce's concert at the Rose Bowl in Pasadena, California, earlier this month in the video below.
