MARIE HELENE vintage era 1960’s long jacket with gingival pockets WELL MADE RARE

So this jacket, I can tell you what I think I know about it after many hours of research and asking for help from others in the vintage clothing hobby! This seems to be from Marie Helene arnauds short lived career designing clothes. There is very little you can find on the clothing she made since it was short lived. Making this an extremely rare jacket if that is what it is. The style and design matches what she was well known for. She was the muse and model for Chanel in the 1950’s and one of there most famous in house models! This jacket has no tags in it other than pictured. It looks like it is a custom made piece. I added the dimensions of my mannequin to help and measurements from the coat. I would say it’s a medium/ large at best! The shiny material inside is perfect purple pinkish tint, that almost seems to move with the light and changes. It’s a silky smooth fabric and vibrant coloring for the time! The fabric that makes the coat is almost like a tweed fabric mixed with wool. I don’t know the fabrics for sure since I am not good at distinguishing them, but you can feel and touch this jacket and be able to tell it’s amazing quality. It’s heavy and well made. It’s in AMAZING condition. This was stored and loved for a long time by the looks of it. The buttons are also put on by buttons on the opposing side making the piece longer lasting. The buttons and everything look original. Please do your own research also! Aprox. Size Pit to pit 17 Length 42 Arms 23 Waist 17
