FWIW, I did act upon the lesson, regarding cheapness, when getting the jacket tailored.

The tailor is an older Italian gentleman who is the go-to guy for highland wear alterations as reccomended by the local highland shop.

He told me there were two options for shortening the sleeves, 1) simply turn over and 2) remove cuff, shorten sleeve and replace cuff. The first option was much cheaper, but would shorten the cuff.

The second option involved more time and labour cost, but maintained the proper cuff length. He suggested the second option as the wise course of action and, having learned my lesson, I agreed it was the way to go.
