My jacket sleeve is about 3 inches too long, the cuff has 4 covered buttons (non-functional) but 4 button holes(still sealed).
I take to my local tailor, I know they don't have buttonhole machine so I said I don't need function buttons and button holes. I want them to cut/open the lining/cuff/placket, fold it and then resemble it, make it look like this just like my other jacket , and sew the button. They said they cannot do it and I need to find someone else do it from sleeve. I thought that's a very simple work. I think it's too risky do it from sleeve. I'm not sure if they are right.
They generally cannot open the sleeve seam to move the cuff up because there isn't enough fabric left along the seam to finish the edge of the cuff. Three inches is a lot of length to take off a cuff, so that alteration is probably best done from the shoulder.
