These are incredibly hard to date in my opinion, i did a reserve image search, i found no other jackets even close to the floral type of design. And they have been around for along time and still are being made. So im stumped. The color palette looks 70s 80s to me , but there is literally no way for me to get a real answet here.
The tag it does have is found on jackets dated from the 60s up until more recent.
Ahhh so i give up i guess
