There is much half-joking commentary on this forum about addiction to kilts and anything kilt related i.e. we "jones" like a junkie when we wait for a kilt to arrive. I've even seen a reference to HDAD (Highland Dress Acquisition Disorder)!

Does anyone else join me in thinking of kilt kollecting as a hobby?

It requires specialized knowledge and vocabulary. There is a community of people with whom we can buy, sell, and trade all things kilt related. The various levels of formality in accessories, the different types of kilts, and the many options for tartan, all allow for conceptualization of a "complete" kollection. This idea, of course, would be highly individual in terms of what anyone would deem complete. But should one actually complete it in terms of breadth, they can always upgrade it in terms of quality!
