Vintage Givenchy Patchwork Abstract Vest

Can't find any details on where this guy is from, when it was made, nothing. But it's a sick piece that's a grey pinstripe suit vest base, with silk back and lining with Givenchy Paris stamped on it. There are some interesting patches on it in different styles, some cool heavy metal buttons, etc. Size I would guess maybe a men's medium. I'm a men's L to XL now and it won't go forward and button on me but my arms go in fine and it looks good unbuttoned. Unique piece for any fellow artsy guys not afraid to stand out, or any Givenchy collectors.
