The reality star, 38, made a surprise appearance in the front row at the 37-year-old tennis pro’s New York Fashion Week show on Tuesday afternoon, just a few days after Williams’ shocking loss at the US Open.
The mobile mogul wore tight, black, leather pants and a liquid metallic tank; it’s unclear whether she had on her new SKIMS shapewear, which she promoted on the “Today” show earlier in the morning, underneath.
She finished her ensemble with her beloved heeled Yeezy flip-flops.
Always on trend, much of what Williams sent down the runway the second show for her eponymous fashion line was covered in sequins, matching Kardashian’s ensemble.
Other famous faces in attendance included Kardashian bestie Jonathon Cheban (seated separately), Gayle King, Ashley Graham and Dascha Polanco.
When Williams took her bow, daughter, Alexis Olympia Ohanian Jr., made a cute cameo.
