Anarchism is funny that way.
It's a collective celebration of individualism, come what may. A short woman with a pair of black wings on her back mounts a bench. The crowd looks her way.

And if you just want this to be an opportunity to dress up in silly clothing and spread your wings, that's fine, too.
