Denise Truscello/WireImageKourtney Kardashian's fashion style took a vampy, edgy turn Saturday night and showed that hard work at the gym certainly pays off.
The 37-year-old Keeping Up With the Kardashians star wore a strapless black cut-out August Getty Atelier crop top, paired with matching shorts, thigh-high black suede boots and a thick black choker, while attending the third night of the grand opening of the Jewel nightclub at the Aria Resort & Casino in Las Vegas with her girlfriends.
The outfit showcased her tight abs. Kourtney has been working out regularly since giving birth to her and ex Scott Disick's third child, son Reign Disick, 1.
"So @kourtneykardash not only took us away for a fun girls night in Vegas but also taught ALL of us girls that you can actually look BETTER after having 3 kids," her hairstylist Jen Atkin, who also works with Khloe Kardashian and other celebs, wrote on Instagram Sunday.
Kourtney was also joined by family friends Malika Haqq and Courtenay Semel. The group arrived shortly after 1 a.m. and were seated at a VIP table near the DJ booth, where they were presented with cocktails and shots, which Kourtney declined. The group Snapchatted and danced as DJs The Chainsmokers performed.
Kourtney and her friends stayed up well past 4 a.m., as seen in a photo she posted on Snapchat.
Rapper Lil Jon, singer Halsey, who wore a white strapless dress adorned with flower embellishments, and Food Network star and celebrity chef Anne Burrell also attended the bash.
