It makes sense that only a very small minority(maybe 1 in 10,000,000) would wear the kilt full-time, and that those who actually own a kilt amounts to maybe 3 in 100,000(Someone has to be buying all those UKs and SWKs). Thus, it seems like you are more likely to be victim of a crime than you are to see a kilt in public. The only thing less common than kilts in public might be religious vestments and kimonos. Naturally I am guessing with the above numbers/ratios, and making a broad generalization.
