I have a fine pair of Crowtree leather trousers, and have been unable to get[1] a jacket made to go with them. Crowtree Leathers are no longer taking orders, due to well-earned retirement. I have a Swift leather jacket, but the waist zip on the jacket doesn't match the one on the pants. Is there an easy way of getting a zip adaptor made up that will bridge the gap? [1] as in "afford" - I won the trousers, and am relatively pikey.
