I live in South Korea, and I'm almost always conscious of my comparatively frumpy clothes I always wear at work compared to my coworkers'. In fact, there are some teachers who seem to have a new outfit every day. Hmm...
I once went to a somewhat fancy "big clothes" store to buy some capri pants for summer (US size 12/14 represent!), and I was asked if I wanted to spread my payments out over xx months (can't remember). I was a little shocked at this proposition. It made me think of putting clothes on layaway at K-mart or Walmart--the difference being that I got to walk away with my clothes then and there.
Of course, I paid my entire bill in one go.
But I think this story is really indicative of the consumer culture here.
