This disco funky bad mamba Jamba was made by a friends grandmother. I feel confident in saying it’s more than likely 100% polyester. As the shell of the jacket is actual shag rug, and the lining of the jacket is polyester. She even sewed a little tag into the seam saying dry, clean only. So if you’re looking to score an amazing one of a kind piece, this has your name all over it. It was custom-made so the best I can do is throw out some measurements. Laying flat the sleeve length is 27” (68.5cm) shoulder width is 22”(56.5cm) top to bottom 24.5”(62cm) width at the bottom 24”(61cm). These are rough measurements so expect an inch give or take. I’m wearing it in one of the photos for size reference. I’m 5’4” with 17 1/2 shoulder width. I’m a 34 E and weigh about 150. I usually buy med tops and 30 or 31 jeans brand depending. Hope that helps! Please feel free to message me if you have any questions and this jacket comes from a smoke for you home
