I recently just inherited a Barbour Beaufort from my grandfather(my dad is too big for it, so it's mine!) and it is a really great jacket. The one major problem is that the sleeves are aggressively short. The sleeves are approximately 3 inches too short. The jacket fits beautifully everywhere else, it's just unfortunate that my grandfather had very short arms.
Now I want to wear this jacket a lot because it's super cool, but mainly because I miss my grandfather and wearing it makes me happy. The jacket carries pretty significant sentimental value to me, and I'd rather not try and sell it on eBay/B&S. After taking the jacket to a tailor, he said that there was nothing to be let out, as the sleeve was cut when it was shortened whenever my grandfather got it shortened. I was thinking about adding some sort of elastic cuff? But I'm not really sure.
Any advice/suggestions would be greatly appreciated.
