Is it feasible to tailor a leather jacket? I have one from toj that I ideally want slimmer in the chest and body, and slightly shorter in the body. I gave measurements slightly too big, and asked for room to layer, which I never do really.
If I were you, I would sell it, take the hit, and order another one that will fit you better.
Shorter in the body may end up looking weird especially if the jacket has pockets in the front.
