Please note that the heroes of the story, led by Jennifer Lawrence's Katniss, are simple farming folk who dress in outfits cobbled together from animal skins and potato sacks. It's only the entitled, narcissistic villains who paint themselves up like Cirque de Soleil performers, right before tuning in to an annual child murder spree for entertainment.
It's one thing to dress up like a movie villain because you think they're badass -- many of us spent at least one Halloween dressed up like Heath Ledger's Joker. But The Hunger Games painted the villains' faces like this to make them look fucking stupid, in contrast with the salt-of-the-Earth heroes. So this would be like dressing up as, say, Jared Leto's Joker on Halloween, and then leaving the costume on the rest of the year.
