Yeah, it's gonna be rough, because they can't take it in from the shoulder since the entire sleeve is spiraled - would completely throw off the design from the back. The sleeve seam needs to match up. MAYBE they can rotate it when the re-attach? It would move the placement of the zipper, but whatever. But a sleeve isn't a tube, I feel like this isn't going to work. Warning: Spoiler! (Click to show)
There's way too much handstitching for them to move the zipper itself up the sleeves, I couldn't ask them to replicate this work. One option might be to just chop and use a shorter zipper, maybe right below the metal cross? Feel like that would screw up the jacket too much, though.
Anyways, I'll talk to tailor. Who likes this long-sleeves business? haha
Hey @nicelynice, I just went and looked at mine, and it does look well-nigh impossible to move the whole sleeve. Chopping could work if you also consider moving the silver cross up proportionally to the loss of material, but I don't know if that is possible given how easily it breaks.
roll 'em up? hang from a tree branch until your arms grow?
Good luck. Please let us know what you end up doing, and how it turns out. Beautiful jacket, btw!
