Vintage YSL jacket

Black nylon vintage jacket via 1980s with details of black and gold buttons and Chinese style trimmings. Long sleeves. Transparency and black typical of Yves Saint Laurent. Tag is white with black graphic Yves Saint Laurent Rive Gauche Made in France Paris. It's a relaxed fit with balloon sleeves. Can be dressed up or down and is perfect for all seasons. Has that runway look. This is that prized staple piece you won't want to give up. I'm struggling with it myself.
