Speaking of warm overcoats, I inherited an extraordinary Viennese overcoat from the early 70s from my father. Reid & Taylor herringbone tweed, has to be at least 20-25oz; with a removable fur lining (I'm guessing it's squirrel, but am not completely sure). It's marked as a EU size 52, which is my size, but it's both way too big for me and also very boxy.
It could never be worn in Australia, even in midwinter - but regardless, I'd be keen to have it altered. The problem is the lining. I'd need to take this to a furrier for an opinion. If they said "can be done", I'd get the outer garment cut down to size first, and then let the furrier go to work. Or should I do it the other way 'round?
This one really has me scratching my head for answers, and so it has hung in the closet (as it hung in my dad's closet - I don't think I ever saw him wear it).
