I am planning on making some vests for the jackets I have or will "covert" to kilt jackets. However, I don't know the proper edicate in regards to vests.

As the fabric for the vests and the jackets are from different sources, they are HIGHLY unlikely to match.

I will be wearing black jackets and tweeds with tartan kilts.
My kilts (on-hand, in finished form or in fabric):
Caledonia (F & K modern)
Carolina (Lochcarron, modern, special weave)
MacNeil (Lochcarron, modern)
Wallace (Lochcarron, modern)
USA Bicentennial (Lochcarron, modern)
X Marks (F & K)

Most of my material for the vests will be solid colored 100% wools.
-So, I may be able to match most of the colors in my tartans

So, what is the proper edicate on coordination?
