fake (?) leather vest

nice spiffy lil stiff fake leather vest with a knit back. the leather is very stiff and convincing i was pretty sure it was real leather but tbh it’s so stiff that i have No idea …. it could be real but i cannot decide ….  i literally cannot find anything about this brand online but i don’t think it’s vintage. the inner front lining is this crazy duochrome iridescent fabric. missing the top button :(. pit to pit measurement is 17.5 inches. waist is 34 inches. length is 23 inches.
