Gents - I'm new to kilt wearing. I just received, over the weekend, my beautiful MacKay Ancient kilt I order while on vacation in Scotland in August from a Haymarket kilt maker. I have most of the accessories I need including two very nice kilt pins.

Here is my dumb question. Is the kilt pin to be pinned through the outer fold of the kilt as well as the inter fold? I’m not sure if the kilt pin acts more functionally by securing the outer fold to the inter fold or if it more ornamental in nature where it only needs to be attached to the outer fold.
