The polo shirt has gone from self-consciously dorky to stylish to nuveau-geek to man's closet cotton staple in the span of 30 years - and it hit on about 20 other designations in that same time; we're just hitting the obvious high points. Breathable, unassuming, unencumbered, classic enough not to catch a disapproving second glance at church but casual enough to wear out with your boys for a morning run for hangover elixir AKA the greasiest sandwich in town. The polo shirt is everything all your best buds should be; it is everyday yet surprising, comfortable yet straight class, homie. How many styles do you own? How many will you?
