looks like a normal flannel to me. flannels were flannels when I was wearing them, not hipster.
and I have no idea what an actual hipster is either, when I think of the word hipster I think of people from Oregon and that show Portlandia, awkward in a social scene and into shit Zooey Deschanel is. basically a new age hippie.
This girl once told me that hispter meant different.
These days hispters aren't really hipsters... something like that.
So according to that definition, sort of?
A "hipster" is liking, wearing, etc/ things that are hip and current. Sometimes they are new to it and just like it because it's "hip", while others have always liked it... and aren't hipsters. I think it's a normal, nice looking flannel shirt.
