Rude boy is a 1970s and 80s British ska subculture aesthetic of sharp suits, pork pie hats, and two-tone music, emerging out of Jamaican and British youth culture. Pork pie hats sit on top. Skinny suit trousers cover the bottoms. Polo shirts and patterned button-up shirts make up the tops. Braces or suspenders hold it together, in a ska-influenced smart-casual register.
