Hip Hop Dancers in the late 70's and early 80's wore LEE JEANS, MOCK NECKS, EL PACA SWEATERS, ADIDA SUITS, PUMAS, PRO KEDS, SWEATSHIRTS with old English letters, and more. But the Graffiti Jackets were one of the main staple of Hip Hop Fashion in the early 80's.
Graffiti Jackets are an extension of Gang Colors. in NYC Colors were not rags, but Biker Jackets same as the biker clubs around the USA.
