i think shorts for when the weather is warm is a good idea----it makes sense. however, i think the style of shorts and their condition would make the difference.
i bowled our associations masters invitational tournament today and the rules call for "proper attire". this is defined in the rules of the tournament as "slacks, except those made of denim, with the pockets on the inside". shirts must be one of three types: 1) polo type with collar, 2) mock t-shirt, or 3) "retro style" bowling shirt. the dress code is strictly enforced----they've sent bowlers away for not complying. i have no problem with this.
