No one can say that Kanye was the first rapper to wear leather pants. Kool Moe D hit it first, Dapper Dan made them popular in Harlem, and then Diddy brought it back in '99 during the 'Mo Money, Mo Problems' era, so they aren't new in hip-hop culture historically. But never have leather pants been so much of a trend that everyone at this year's Summer Jam had some semblance of leather on, be it leather sweats, a leather tee, or leather tank top. Yeezy's imprint on hip-hop and pop culture style has never been so apparent.
