Ron -please dont wear a sash, if you want a Plaid get on -a nice fringed one, normally grooms wear one over the left shoulder, In the unlikely event your a clan chief then wear it on the right.
I just looked at the pic and the guy looks like hes auditioning for a role as a stereotypical Scotsman in some kind of comedy film, with his pipers
Glangarry and what appears to be a womens blouse. !!
I know some people have said theres noting "wrong" with wearing a tartan sash but it doesnt look right. leave it for the lassies!!! check out the "blue hawaii" it would definatly raise a smile!!!
