A couple of random thoughts:
(1) Cooley has it exactly right about the old pink Lacostes: they were the perfect shade, sadly now extinct. Most of the colors I see offered these days don't appeal to me, particularly the "heathered" shades. Still, I've always tended to stick with white and navy anyway.
(2) Unlike many here, it seems, I'm comfortable with a slightly baggy fit to my polos. I do not wish to show off my pecs (pace, FrankDC), such as they are, nor do I like feeling a tight grip around my biceps. Long tails are similarly a requirement.
(3) I'm somewhat curious about these -- anyone tried 'em? At twice the price of their regular polo, they must be decent. What makes a golf shirt different from a normal polo?
(4) I typically buy a couple of new polos each year. These get worn to dinner or other casual occasions, while the previous years' models get pushed down the ladder, first to errand shirts, then to fishing/car washing/gardening shirts. Three years is about the maximum lifespan. I see polos as the trad's version of the ubiquitous t-shirt. For that reason, I have a hard time spending much on them (though I might make an exception for those Grass Court premium piques, if they're really like the Lacostes of old).
