As has already been said, there really are no written rules on this sort of thing but, to my mind, there are things we do which can distrurb the eye of the beholder!

I like to think that I usually (if not always) present the best image I possibly can to 'Joe Public' when out 'there', and so check my appearance in a full-length mirror before leaving the house.

One thing I have learned over the years is to always tuck in my shirts, whether they be T-Shirts, Polo Shirts, dress shirts or casual shirts, when kilted. Somehow, one needs to define the waist-line to achieve what I have been referring to here for years: visual balance. If the natural waistline cannot be seen, the alternative feature is the hem or bottom of the shirt which, being lower, lengthens the appearance of the torso and shortens the appearance of the legs. In other words, the visual balance of the wearer's body is distorted - in some cases, considerably.

Take time to check this out for yourself - look at your appearance in a full-length mirror and see yourself from the viewpoint of a stranger coming across you on the pavement/sidewalk. You know where your waistline is, but the stranger can only guess - not that 99.9% of them wll consciously look for your waistline but, unconsciously they will. If you are un-tucked, what will they or, in this instance, you see? A guy with an overlong torso and stubby legs!!

Everyone of us must dress according to our own wishes, of course but, if asked for advice, I will always answer, "Tuck your shirt in!"

Take care,
Ham.
