Here are a few examples from the Vintage photo thread of how to wear a dirk with a coatee

Many Atholl Highlanders still attend the the RCB, wearing the same uniform.

I also have a photo from this years Burns Dinner where I wore my own dirk with a Montrose Doublet, normally I would forgo such extravagance however I was doing the Address to the Haggis and so the dirk was appropriate. It was not on the sporran strap but on the dress belt.
