I have repaired a lot of clothing from cleaning it to sewing. I’m not an expert but I can offer advice. If you have any questions I can recommend what to do or where to find what to do. So, that said, ask me some questions. Or share your insight. All is appreciated.
I found the coat above, re sewed the lining and added mink cuffs to it with a matching collar from the 50s. Doesn’t have to be about repair, could be any kind of alteration.
