Yes, but authenticity as value signaling, not as a commitment to behave without unnecessary layers.
I lived in a meditation center for a year, and I saw some people there that claimed to be authentic, and worked to look like the stereotype. But they were actually hiding a desire for materialism and the failure to live up to it behind the apparent choice of rejecting it.
Style and looks is just what it is, a shell. And some people use clothing to augment what they are lacking in their character. And smart people can see through that.

Irony can be pretty ironic.
