Don't remember where I heard or read it but the old kilts had only 2 straps. One for under apron through slot and one for over apron. The kilt pin was used to secure the front of the 2 strap kilt. With the 3 strap method of securing at hip line the kilt pin was just decoration because the 2nd strap on the over apron would keep it down (along with sporron) in the event of a good wind (well, mostly down!).

Again...personal choice. I don't wear a kilt pin...mainly because I haven't really found one I like enough. I wear the Clan belt and a Clan kilt pin would be overkill.
