Just my twa bob:

The badge that you and FM describe is in fact, a blazer badge. In the old days, bullion regimental/school/organisational badges were sewn directly to a blazer. Sometime in the last 10-20 years, companies started making them with clutchbacks (affectionally known as as "dammits") so one would not have to sew the badge to a blazer. I have one like this for our local St. Andrew's Society, and another for an organisation of altar servers/acolytes that I belong to in the Episcopal Church. Oddly enough, I find myself wearing them less and less.

In my opinion, blazer badges are just too big to be worn in place of a kilt pin. They are designed, in size and material (bullion wire) to be worn on the pocket of a blazer/club jacket.

Also, I'm not big on wearing items traditionally associated with Highland attire with contemporary kilts such a Utilikilt, because the inventor of said garment fully admits they were never based on a traditional Scottish kilt. Now again, that's just my opinion, and I know it's not a popular one around here. If you choose to do it -- great. I don't own a contemporary kilt, and probably never will -- and if I did, I wouln't try to "convert" it to a traditional kilt -- I've heard Hamish even say this that he avoids trappings of Highland attire with his modern kilts.

So again -- this is just my observations. Your mileage may very.

Respectfully,

Todd
