Vintage 60s homemade jacket, Size L

i’m so obsessed with this jacket, it’s insane. It took me a while to figure out when this was made but i’m pretty confident it’s from the 1960s and was made at home by an experienced dressmaker!

•This is in great condition! There’s one almost-hole in the back by the bottom, and a small
thin black line behind one of the sleeves
•Super sturdy construction! This truly was made by someone who wanted this jacket to last a lifetime
•Two slash pockets
•Brass Conmar Conmatic zipper down the front
•Collared
•Snap buttons on the side of the waist so you can adjust it to your liking
•Knit sleeve cuffs
•It looks like there were two other patches on the chest that were then layer removed (one droplet shaped and one square, i’m thinking that the original owner probably changed out the patches to fit whatever their style was as time went on) but the stitch marks aren’t too noticeable from the outside
•No size marked, shown on a size 10 and fit well but peep the measurements below to ensure a perfect fit❤️
-40” waist
