When I was a kid my favourite garment in the world was a suede vest similar to this one - so perfect and fun.
Unlined caramel suede with dark brown piping that appears to be cotton along all seams. Seams on top of the shoulders and running from the outer edge of the shoulders to the hem on both the front and back with a panel on the side extending outwards under the armpit. No fastenings, open front.
Labelled as size 5, no country of origin or materials visible on label.
