I purchased this really nice gold label a couple years ago and would probably wear it more if it wasnt so long. It’s 29 1/2” in back length from the base of the collar. Everything else fits pretty well. My Langlitz is 26 1/2” and I like the fit. Is it worth the cost of the old Brooks to have it altered? I’m 5’8”. Thanks, T4
If you otherwise love the jacket and will be wearing it more, then yes. The zipper looks like it can take the alteration. If new zipper were needed then I'd think twice because it would be about $75 extra, plus the cost of the new zipper.
I say Yes. Especially because the jacket looks to be in such good condition. If you get it just the way you want it you can wear it for many many years.
How long are the sleeves? That is a tall size and usually the sleeves of these are 28 inches long, so that's worth considering. I think cutting it back 3 to 4 inches might make it look off.
