Arguably one of the most influential bands of the last 15 years, The Strokes have defined both the musical and style agendas of their millions of fans — and they're showing no sign of stopping. Frontman Julian Casablancas made us all buy skinny jeans and blazers in the early 2000s, then pointy black shoes and wayfarers after that. Now he's going to force us all to snag some hectic Hawaiian shirts for extra summer fun, not that we needed any persuasion.

Performing on stage at The Governors Ball Music Festival in the band's hometown of NYC, Casablancas rocked an excellent shirt and nailed the rest of his look by teaming it with a pair of slim-fit stone-wash denim jeans and some classic Converse hi-tops. It's this summer's best, brightest and easiest look to pull off. Get involved.
