VINTAGE Sequin blazer

1970s VINTAGE Brown and orange sequin blazer. Full sequins. I got it from a consignment shop and theres no tags so i dont know much about it. Its like a crochet yarn type design. Its woven like no solid fabric. Its brown orange and black zig zag pattern with matching sequins along the lines. Its got a brown silk lapel/piping all the way around the neck down the front to the bottom. I wear a small and its perfectly tight on me so id say its a size XS/S. no signs of wear that I CAN SEE.
