2 Chainz is a rapper, TV show host, and otherwise loud personality.
A while back, there was a reddit thread asking whose style we could appreciate, but not pull off ourselves. At the time, I said Hendrix, but 2 Chainz would have also been a very relevant answer. His style is loud, unique, and expensive as hell. Of course, he probably doesn't pay to wear Gucci and Supreme, but it's still an aspect of his style that's not accessible to all of us. But that doesn't mean we can't appreciate and draw inspiration from it.
He's known for wearing (at least) two chains at (almost) all times. One chain symbolizes the man he is; the other symbolizes the man he aspires to be. His style involves loud bombers, headbands, sunglasses, and jewelry.
He's the host of Vice's Most Expensivest (GQ's Most Expensivest Shit), where he reviews food, weed, clothing, and everything else that might be expensive.
