It depends on the particular course where you are playing, but most private clubs require your shirts have both a collar and sleeves. Shorts are also usually required to be Bermuda length.
Skirts tend to hit slightly above the knee.
Jeans and cut-offs are not allowed at most private clubs. Today there is much more flexibility in golf clothing, so it really depends on your personal style. Cashmere is now totally acceptable on and off the course, as are leather and suede. Try our pink V-neck mini cable cashmere sweater with a pair of resort lime suede shorts for a classic preppy attitude. With the new popularity of the sport, fashion is taking inspiration from the golf course as well as influencing new styles to be worn during play.
