It was a hot summer day. A coworker told me that I shouldn’t wear short sleeve dress shirts any more because that wasn’t a mature thing to wear. I noted that I wore short sleeves on my mission. When you go to the temple, you must wear long sleeve shirts or are asked to change. Why do they only allow long sleeve white shirts in the temple? Are short sleeve dress shirts just for the young? Is my friend right? Should men only wear long sleeve dress shirts?
