Very little can be removed or added at the sleeve's cuff-end without completely destroying the balance and proportion from bottom-most button to sleeve-end. Perhaps one-quarter inch at most
is possible IN GENERAL
Shortening from the shoulder is possible if you trust your tailor and want to invest (on average) $125.00 per sleeve. The jacket should have some sort of value in your mind for an investment in this procedure.
Lengthening from the shoulder? Forget it! It's highly unlikely! Find another jacket!
