Does anyone have advice on what to look for in a pocket square (material, craftmanship, pricing, etc.) and have suggestions on where to get reasonably priced ones? I figure I can just pick one up at Nordstrom, Macy's, or Bloomingdales. I just don't want to overpay for something so simple. Or what about ordering a $9.99 one on the web for a 100% silk one?
