Kanye West made a surprise appearance during 2 Chainz's set at the Pace University Homecoming a few days ago. While onstage, Yeezy wore a crewneck sweatshirt from the Diamond Suply Co. x Ibn Jasper collection and a gold studded hat from Stampd LA.

The sweater, which retailed for $68, was released with the full line last weekend and is already sold out. But the hat is still available online for $95 if you're interested.
