Until a year or two ago, I never so much as glanced at cotton pocket squares, preferring linen. That changed when I was formally introduced to pochettes from the venerable French firm of Simonnot-Godard.
The next time you're browsing the pocket squares at Alan Flusser or Paul Stuart in New York, Lanvin in Paris or Turnbull & Asser anywhere, pay attention to the cotton offerings. It's likely that the better ones are Simonnot-Godard products that were made the old fashioned way, to very high standards. Beautiful stuff. Reasonably priced as these things go. And recommended.
