Plaid Brooch with the great kilt

[OC Richard]

Didn't plaid brooches come in after the great kilt became extinct? Weren't great kilts secured at the shoulder with a ribbon?

It always bugs me to see things like Outlander with huge Victorian "Gaelic Revival" brooches worn to secure 18th century great kilts.

Or the style of brooches worn hundreds of years, perhaps thousands of years, before the great kilt appeared in Scotland. (Iron Age brooches and the like.)

Throughout the Victorian era and even today, in the army, the so-called "drummers plaid" (actually worn by all Other Ranks, not just drummers) which sort of recreates the look of the old great kilt is held at the shoulder with a ribbon rather than a brooch. (Distinct from the belted plaid worn by officers from the retirement of the great kilt to today.)

The last vestige of the military great kilt, the plaid worn by ORs in Full Dress. Note there's no fringe and no brooch.
