Here in Canuckistan, a kilt is considered pretty much a luxury item, but that is based on history and not current economic levels. It's changing slowly, but here the unkilted people attending, say, a Highland Games are still quite surprised if you wear one to the Games and are not an organizer or in a band or other such group and that is mostly because it hasn't entered the Celtic public's consciousness that they are within general economic reach now. I remember how suprised I was when I realised I could buy a new one! From what I know about Scotland and from comments seen here, I would say that is pretty much true in Scotland, or perhaps even more so. The first rule of a helping profession is of course to establish a personal trust relationship with the clients and if a kilt will get in the way of that I have to make the sad recommendation that you don't wear one. On the job I mean.
