A relatively new word from the world of fashion might work
normcore
embracing sameness deliberately as a new way of being cool, rather than striving for “difference” or “authenticity.”
... is how it's defined in a New York article introducing the term.
(The inventors of the word say the meaning's been changed.)
Normcore is now in a journalism stylebook and written up by Oxford dictionaries. And the Wikipedia article is quite good.
