slick rick [the rapper] wears an eyepatch for medical reasons. he dresses really snazzy too.
he might overdo it when he performs, but its congruent with his style and personality.
i don't think most of us can get away with dressing like him though.
as for medical related peacocking...i tend to injure and cut myself alot due to breakdancing and open water dives.[i get cut up real badly on the rocks] so i often wrap my hands or whatever is cut up in waterproof medical tape. it sticks out, and people always ask me what happened to my _______...in which i would respond with a DHV story. but sometimes when its my palms or knuckles wrapped up in bandages, i feel like i have to go fight somebody haha.
