For me it depends on the work I'm doing, the weather, and whether I am seeing clients and need to be smart, or working around the workshop where I need to be comfy.

If I'm going out I'll wear a tartan and accessorise it according to where I'm going.

It's great to have choices, and as long as I'm kilted, I'm a happy man.
I'm at 15 kilts at present, a few more to go to catch up with Hamish
