Ham:
I was successful on finding a kilt jacket last week while walking the Royal Mile during a thunderstorm. I didn't have too much time to shop between the tour and the Tattoo that night so it felt as if my wife and I were "running" versus walking the Royal Mile. After several laps around the Mile and checking out all the shops suggested during the course of this discussion, I finally found my informal wool kilt jacket at Nicholson. Must have been a run on jackets just before I arrived because none of the other shop had my size.
to answer Ham's inquiry about what type of jacket I was looking for, I already have my formal jacket-Sheriffmer complete with jabot so I needed an informal jacket for everyday wear.

Our visit to Scotland was just great and the Tattoo was fantastic! One disappointment, though-I expected to see more kilts walking around. Sadly, only kilts I saw were being worn by the shopkeepers.
