Corteiz (also stylized as Crtz) is a London-based streetwear brand founded by Clint, a British-Nigerian designer, who began the label in 2017. It initially gained traction through guerrilla marketing tactics and exclusivity, with Clint using social media, especially Twitter and Instagram, to build anticipation and foster a loyal community. The brand’s slogan “RULES THE WORLD” (RTW) became a symbol of rebellion and individuality, resonating with a generation seeking authenticity in fashion.
