btw, I used to do fine with land's end polos when I worked in the rough & tumble world of special ed. (dressy enough for those picnics and other outdoor trips, as I always worked summers). Not so chi-chi, I know but can't beat their bang/buck.
The BEST polo I've ever had hands down was a long sleeve Club Room, made in china and purchased at Macys in 1998 for a whopping $50. (It may have been on sale too....can't recall for sure). It just recently started showing signs of wear....It is a nice soft cotton, feels more like cashmere than any fine wools I've seen, and is the perfect thickness - not too thick or too thin.
I've searched high and low in Macys and everywhere else for a cotton polo like this and have never found its equal. I may email them with the style number to see if they still make it......or maybe I can have it cloned by a tailor!
