Golfwear settled into a basic uniform still recognizable today: a short-sleeved knitted shirt, with a longer tail; lightweight slacks of various colors; sturdy shoes with spiked soles; and a snap-brim hat in porkpie shape. Waist-length jackets, inspired by the famous Eisenhower jacket of World War II appeared on the course. With roomy shoulders for a healthy swing and a waistband for a snug fit, they were made of water-repellent cotton. Shorts became acceptable, usually tan or khaki, but also checkered Bermudas. The shell-stitch alpaca cardigan sweater, with bell-shaped sleeves for easy swinging, became a staple.
