Isaac, I see you did not post this in the Advice forum, but please allow me to offer some anyway. A jacket cut for the kilt is a good idea. If your present circumstances do not allow for purchasing a new one, maybe your handy wife can help you convert an old suit coat. Nobody is going to die or to arrest you for wearing a saxon-length jacket with your kilt, but you are denying people the pleasure of seeing your pleats. Think of them.
