Eaton 70s Vintage 100% Wool Fair Isle Cardigan, M

This cardigan is decades old, I’ve had it for close to 30 years and it looks like I just bought it. Worn a handful of times and washed by hand. Very pretty, feminine design, unbelievably warm and in immaculate condition for its age. Size Medium but fits more like a small to me, please look at all pictures for measurements and condition. I just wore this sweater recently but haven’t washed it so it smells of perfume; also noticed two faint stains that would easily come off with a washing.
