Wiz Khalifa hit the Made in America Festival stage in Philadelphia yesterday rocking what may be his new favorite brand: Kokon to Zai. The rapper performed in a black and white shirt from the Fall/Winter 2013 collection. 

Now, this is definitely not the first time we've seen Wiz rock KTZ. In fact, he's been on a bit of a KTZ-kick lately, even getting his new wife Amber Rose in on it—the couple arrived at Hot 97 for an interview with Angie Martinez in matching outfits.

What do you think of his look though? Do you prefer this over his previous hippe, rock style?

So far, in addition to Wiz, we've seen the likes of Jay Z, Kanye West, A$AP Rocky, and even Trinidad James co-sign KTZ. Who will be next? Your guess is as good as ours, but if we know one thing it's that the list is bound to get bigger.
