I was reading an article about how men should NOT tuck in their shirts if the shirt is worn as casual wear.
I often wear suits with a black tee shirt, tucked in. I have some great Cabana style shirts that are always worn over the belt. If I'm playing some sport, I would never tuck in a tee shirt.
I looked online after I read the article and it seems some are very firm on their position...... And while we're at it, should men wear a belt with jeans or with dress slacks?
