I thought hipster was essentially supposed to be someone vapid and style obsessed at any given time. Dandies would have been hipsters by my understanding. It's a focus on appearance and also whatever is a current trend of the times so they might also include interests or hobbies as well, the point is the term is used pejoratively because the interests or the style adopted by these people is considered surface level and inauthentic because it is primarily based upon the recency of widespread adoption of whatever it is.
Although, the one in Washington (state, USA, Earth, Solar system, Orion Arm, Milky Way, Local Group, Virgo Supercluster, Laniakea Supercluster, The Universe) isn't full of hipsters.
