when it's really just ironic because they're belonging to a group by being a hipster in the first place, which defeats the purpose they have to not be mainstream.
They often shop at thrift stores, like bands like arcade fire, but they won an award so I guess they're not "cool" anymore because they're mainstream. They spend a ton of money to look like hobos basically from going to thrift stores.
They wear oldass clothes to look "trendy".
They are often found all over San Francisco.
Their music often defines them.
Basically, they are going out of their way just to look different because different=cool
