A black choker necklace and some cornrows completed the reality star's interesting look, as she arrived at the venue hand-in-hand with boyfriend Tyga.
Once inside, Jenner took to Snapchat to explain her unique ensemble.
"So, Jordyn and T forced me out the house tonight. I am having a lot of fun, but the only outfit I could find is this biga** T-shirt," she said in a bathroom mirror shot. "I do love these new Pumas, though. But girl…"
While Jenner was happy to show off her look, her sister Kim Kardashian West kept a much lower profile at the show. The mother of two tried to avoid photographers in a black Saint Pablo baseball cap as she arrived at the Forum to quietly cheer on her husband.
The Kardashian-Jenner clan weren't the only stars in attendance at West's show.
Jenna Dewan-Tatum, Jessica Alba and her husband, Cash Warren, Pharrell Williams and his wife, Helen Lasichanh, and Hilary Duff and her boyfriend, Jason Walsh, also flocked to the Forum for a little Yeezy.
