Hello, and thank you for looking at this. Has anyone ever seen a label like this? It is on a 60's/70's disco blouse. It says LANVIN and there is a tag behind it. Is this a knock-off of LANVIN PARIS or maybe a different company named LANVIN? Is anyone aware of knock-off clothing made in the 60's/70's with this label? I am including a picture of the front and back of the blouse. As you can see, the size is washed away...More info may have been washed away. Thanks again.
