This Weather

Last day of spring. Ninety Days of summer plus warm early autumn next.

See weather maps and forecasts (east of the Mississippi River USA), particularly dew points.

Amerikilt (OD is lighter than khaki). Or Sport Kilt poly-cotton, hiking, or (gulp!) tropical.

(Very) casual outfit: Kilt, sandals. Only.

Sorry, wool or acrylic quite useless.

Even USAK PV Casual marginal.

The (USA) great divide -- is not between Traditional/Heritage vs. Contemporary/Modern; but rather about comfort per climate.
