I think a lot of people covered what you need, but the most important thing needs to be emphasized.
Hipster is about where you live, first and foremost. For instance, you can be wearing your same perfected hipster outfit in these two places:
1. Statesboro, GA - you look like a poorly dressed retard
2. Portland, OR - you are irony, personified
For instance, where I come from originally (Philadelphia), a real hipster has a loft in Fishtown. If he's riding his fixie around the Northeast, he just looks like an idiot.
You want to be a hipster? Move to an existing hipster hive. Hipsters do not originate in place, they congregate with other hipsters.
