This is an authentic vintage vest. I am guessing the 1940s. best for a 25"-26" waist. 32" bust. 34" could squeeze into it though because I did 😅 excellent condition! Just missing the bottom button. I either didn't use that, secured with a safety pin, or was wearing a belt over top. I can't find a content tag but I am going to say a wool blend. about 18" long.
