Long Faux-Cashmere Coat

thrifted this coat and ended up not wearing it! bought it as-is, condition is good has pockets and a coral satin lining the seam at the bottom hem for some reason is not sewn together (see video) there’s also a small stain on the back bottom right (see pic #7), but other than those two things there are no flaws that I’ve found not sure what the size is but it fits me like a S/M; I’m 5’2” for reference!
