Would seem pretty accurate to me.
I myself am not self-employed, however when I do go out to get some side work, I always dress in a way that I feel the potential costomer will find most appealing. However on the flip side if you can bring some attention to yourself with out it being repulsive to the costomer then you are more likely to be remembered when he or she is looking for some more work in the future.
Either way I must concur that this would offer the greatest challenge to the wearing of the kilt.
