First traditional Kilt

[ThistleDown]

I'm not sure of the origin of the 'fly plaid' (I'm sure OC Richard will inform us), but it is virtually unknown today -- in Scotland -- except as supplied as an add-on by wedding outfitters. An unnecessary bit of unnecessary, even in formal settings. But if you wish to wear one, it should be of the same tartan as your kilt. Interestingly enough, in the days when day plaids were commonly carried, they sometimes differed in weight (but not tartan) from the kilt. I've no confirmed idea why, but perhaps because the plaid was a blanket intended for its function and not for fashion?
