Michelle by Amalfi set from the 70s. unsure of fiber content- but it is a thicker material. probably a polyester blend. This set includes a vest cropped by myself from the original longer vest. The vest is lined with a yellow fabric. The pants are original design with an elastic waistband. This set is great for layering.
