DH has to go away for a few days and needs to wear his suit. At present when he is at work he either wears a short sleeve buttoned down collar - open at the neck or a Polo shirt. Well TBH, he is having great difficulty in choosing a shirt, he has 2 - 1 with long sleeves and 1 with short sleeves both with ties that match. He is worried about being warm, so I suggested the short sleeve, but he is worried that it wont look so smart as the long sleeve. My opinion is, that if he is hot and sweaty then he will not be looking very smart anyway!
So, is there a code of dress when wearing a suit?
