Warm meets cool. The deep blue has dark water before sunset; the sand tan counters with beach sand, dry. The contrast is the point. The cotton-modal blend drapes like a tee that costs twice as much. The driving range doesn't require a dress code but you showed up with one anyway. Course to clubhouse in the same outfit. Nobody's changing in the parking lot.
Finish with white or gray spikeless golf shoes and a braided belt.
