OK, I hit the local thrift stores today (the conference is the week of 8/21, so I need to get cracking!). Not too many selections, especially in tweed, which I think will be the most versatile. It is difficult to find a jacket that will:

1) fit correctly (especially with my gorilla arms)
2) match the most kilts
3) have patch pockets (almost impossible)
4) look good to my eye

Anyway, I did find the jacket below and will be following Alan H's directions for modifying it. I actually did/do want a light colored jacket for even mor casual occasions and may try to get the one in the first pic and modify it. Since I spent a grand total of $2.71 on this jacket, I can afford to make a mistake or two with it. The biggest concern I have is moving te pockets. Patch pockets are easy, just use a seam ripper to take them off and re-sew them where you want. This has lash pockets. However, it has no vents, and is tailored tight at the waist. So I am hoping I can take the material I cut off and make patch pockets that hide the existing slash ones.

Anyway, here are the pics, first a closeup to show the color and pattern:


The front:


And the back:




As a sidenote, I did determine that a double breasted jacket that was smaller than you normally wear, or a 3 button jacket smaller than you wear (like this on me) will actually eliminate some of the tailoring. Not vents in the back is also a plus.
