I'm a proud lemming owner of the Spiegel jacket and quite happy with the purchase. The only thing holding it back from perfection is the length of the sleeves. I didn't really notice how long they look until I tried to snap a picture. I like the jacket enough to invest in the sleeve shortening alteration, but I'm nervous about having the jacket ruined.
Does your regular tailor do leather alterations? I normally have my alterations done at the dry cleaner who I believe just sends them out. Should I search out someone who specializes in leather? How much should I expect this to cost?
