Please refer to the images for details. It's polyester. I don't know the definition of chiffon, but it's a similar thinness. When I examined the pattern with a loupe, it looked like jacquard georgette, but I don't know for sure. Accurate color reproduction is not possible. Also, I am unfamiliar with fabric names, fabric thickness definitions, color names, product names, etc., and I do not have detailed product knowledge. There may be incorrect descriptions, so please use this information with discretion and only if you are satisfied. There are wrinkles and fold marks from storage.
