Frank ‘the Butcher’ Rivera: streetwear’s rising star

He can easily recall the moment when he officially transformed himself from Frank Rivera, metal shop supervisor, to Frank “The Butcher’’ Rivera, streetwear and sneaker designer. “My brother passed away in 2005 in a car accident,’’ Rivera says. “He was 21 years old. That was it. At that point, I realized that I wasn’t going to be around forever. I didn’t want to just get by anymore.’’
