The Dockers Alpha Khaki is a classic, reserved for the more discerning and distinguished gentleman. It’s a bit more sturdy than your average chino, and the fit is timeless Ivy League style: a nice taper, but not overly so.
They look smart with pretty much anything, too. Wallabees, desert boots, deck shoes, canvas thingies, trainers, weirdly cool orthopedic shoes, whatever.
Channel your inner JFK and get some ordered. Or, if you live nearby, go in the shop and buy them there, like they did in the olden days.
