Yves Saint Laurent mesh formal overcoat

This is an exquisite vintage Yves Saint Laurent metallic mesh hand woven green/gold formal overcoat/long jacket with 3 pockets-It is European size 38 which is about a small to medium in US but this is an oversize long dressy jacket-I have never used it. It was in my closet but the original tags are not attached! I do not remember the exact price but it was over $ 3500 during late 70's or early 80's but it is authentic and in excellent condition
