I seem to remember being told that the only tartan to be worn above the waist is either a waistcoat or a fly plaid, but I have to admit it looks good on him.

Also congratulations on obtaining a daughter-in-law. I have three, and as of the current moment, no sons-in-law, but my daughter seems to be working on that, however.

Also congratulations to the new couple, from a pair of 50+ year veterans.
