Dress like the superhero who has a hard time being a superhero.

Yes, Spider-Man is a superhero, but he's not deriving any enjoyment from it. 

In fact, since becoming a superhero, his life is forever complicated by a steady stream of vengeance-seeking, animal-themed supervillains.

Unfortunately, if he throws away the costume and proclaims something silly like, "SPIDER-MAN NO MORE," he has no choice but to reclaim the now putrid costume and perform at children's Birthday parties to pay the rent.
