Here's a video of
"Austin Style". One of the quotes I think sums up Austin (or at least Austin's hipster scene):
"I like to shop at used clothing stores. I rarely spend more than like $40 or $50 on any piece of clothing" (edited for articulateness)
At the used clothing stores I shop at, I've gotten an entire suit for $20. A three-piece suit. Maybe if you went to Saver's instead of some "vintage boutique" you'd be able to get an ugly sundress for less than $50...
