why does gregory porter always wear a hat

Gregory Porter always wears a hat to cover up scars from skin surgery he underwent. This hat, specifically a Kangol Summer Spitfire, has become his signature look and a kind of "security blanket" for him. He started wearing it for practical reasons related to the scars but grew to appreciate the comfort and style it gave him. He is recognized more by his hat than without it, and he has openly discussed that the hat is now part of his identity as a jazz artist. The hat also includes a modified strap that covers his ears and chin, originally part of the reason for wearing it due to the surgery.
