Has anyone tried wearing a cumberbun (and a formal jacket) with a kilt?

I finally found where my DW packed away my US Air Force mess dress uniform. This formal outfit has a short jacket, which is like the Eton jacket some members recently purchased, so it will work well with a kilt. However, a cumberbun, instead of a vest/waistcoat, is also part of the uniform and I am undecided whether it would look good with a kilt or not.

I would post a picture of this combination, but I haven't found the cumberbun yet. I am trying to decide if I should buy another cumberbun or try to find a vest to go with the jacket.

What do you think?
