Dirk plus Braemar

[MacMillan of Rathdown]

In answer to you question, no, there is no way of satisfactorily wearing a dirk with your jacket. Due to the length and cut of your jacket your dirk will become hung up if you wear it, unless it is hung virtually in line with the centre of your body, in which case it will run afoul of your sporran.

Dirks worn with evening dress should be ornate. Since ornate equals expensive they are best reserved for those occasions when full highland dress would be worn-- in other words "white tie" events. Powder horns, swords, and pistols being no longer worn the dirk is the last vestige of Victorian/Edwardian highland romanticism. They are probably better cherished as family heirlooms and object d'art than worn to the local Burns Supper.

You might be able to attach it to the sporran, as you have some experience with them. Otherwise you would need some sort of baldric worn over the jacket, which would likely look rather odd.

I could think of a couple other ways to wear one, but they would likely be uncomfortable and the dirk would be concealed, which would probably defeat the purpose of wearing it in the first place, unless you are expecting trouble at Burn's Night, and could also run you afoul of the local constabulary.
