I think that there are two or even three different issues here. They may all tie together, but probably don't.

Firstly, is the kilt a luxury item? By strict definition, probably yes. There are just too many trades, professions, jobs and tasks where the kilt is more of a hindrance than a help for it to be anything but a luxury.

Secondly, unless one is in the know - a tartan kilt is a tartan kilt. The average man in the street (be he Scotsman or not) cannot tell one kilt from another. Unless they know about different fabrics, most people will assume that what they are seeing is wool. You can wear a cheap off the peg kilt or a hand sewn tank - people will see a kilt.

Thirdly, Jimmy has given few clues as to who his clients are. I have, in the past, had to work with the unemployed and the unemployable, the homeless and the dispossessed, substance abusers and those with mental and physical disabilities. People covered in their own urine, vomit and feces. Did I dress like them - No. I wore a suit, shirt and tie and polished shoes. They expected me to look and act professionally and that is what they got. Dressing down to their level would only have been condescending and insulting.

Do these three things tie together? I don't know. Jimmy must make up his own mind as to what is appropriate at his place of work. His clients should be his issue, if the kilt becomes the issue, then he should probably stick to trousers.
