THCD everyday for inspiration?

[IsaacW]

You're wearing a kilt. Folks are going to make an association with Scotland!

I just take off my tie, jacket, and belt and roll my sleeves if the weather is warm but tolerable:

If it's really hot I usually wear lighter weight kilt hose and casual loafers (LL Bean camp mocs), skip the flashes, sgian dubh, and belt, and wear an open collar shirt with my shirt sleeves rolled up. I wear one of my simpler leather daywear sporrans.

David, has good advice above. You could even wear a linen or cotton waistcoat with little additional warmth. I have seen some in a nice herringbone that almost appear as a tweed.

Here was a waistcoat I got on clearance that is a linen cotton mix, IIRC, and is a nice herringbone. It is lightweight and cool. Pardon some of the other fashion sense in the image... I have progressed a bit in THCD since this photo was taken.
