O C Richard, thanks for showing pew carving in cornish church, exact garb not clear.I understand original cornish kilt was full 24ft wrap fastened with two clasps, roman style, not one clasp scottish style.
twin chanter shown on cornish pipes, mellower than Scottish bagpipes.
Found cornovi cornish kilts in cornwall. Informed me thay could make me black cornish kilt in top of range 8 yard 16 ounce , does not seem as thick as old highland regimental military kilt. Worth noting Cornovi cornish kilts are measured in cornwall and made in glasgow with cornovi label with cornish black and white flag. Perhaps our experts could comment.

My theory is that my ancestors were seamen by the name of Cook ,of Stuart Clan,if it is accepted as a true clan,and Poole records show Captain John Cook, son of a,or the, Captain James Cook drowned Poole Harbour, Dorset Southern England, at time of 1745 troubles.
Cooks may have worked grand banks from Poole Harbour. Millers were privateers shipwrecked in dorset.Perhaps I should be the first to wear a black Dorset kilt in memory of the loss of scottish mariners.Exactly the same as modern traditional style cornish or Scottish plain black kilt. Good reason for wearing kilt with traditional day warm day kilt jacket.
