Vintage Givenchy men's button-down shirt, red and white, size M

I love the drape on this vintage short-sleeve shirt. Almost silky to the touch even though it's 100% polyester. Missing a button at the very top and very bottom, but not noticeable when wearing. Also a small snag at the bottom (see pic). Label says large but it's really a medium, a bit on the short side (see measurement pic).
