As a traditionalist, I do find them slightly strange: however there are two points arising:-

First if a reputed clothier such as Pringle are prepared to devote so much time and money to putting them on show, it suggests that they are seeing a market extending beyond the traditional kilt wearer. For if merely trying to attract attention, they could have just shown one amongst their more general clothing range. So whilst their examples might be rather extreme, it is indicative of a growing kilt wearing population, and that such a population is appearing upon the horizon of reputed clothiers.

Secondly, if such variants as the Utilikilt are accepted, are there any grounds for not accepting the Pringle variants?
