I'm a Landscape Designer and foreman so it was easy for me to be kilted at work. I asked the owner of the company (and also my supervisor) and was told "If you're man enough, go ahead". It's been almost a year now and so far it's been over 90% positive.
Being kilted at work is not something everyone (even if they want to) can do. There may be dress codes, safety regulations and other things that prevent it. Enjoy wearing the kilt whenever you can, even if it's not full time.
