Givenchy vintage men’s Dress Shirt

Rare vintage GIVENCHY men’s dress shirt 👔 EUC 15.5/34. This is from my family and definitely GIVENCHY. It’s just a little too boxy for my husband’s taste, so he’s never worn it. I’m guessing it is circa 1970s or 1980s but am NOT an expert on vintage shirts...LOL. No rips, stains or holes; all the buttons are intact. Beautiful piece; could even be oversized shirt for women. I’m too short to work it 😔😔😮
