Blair Vintage Red and Black Plaid Button Down Shirt Long sleeve Baggy Sleeve LG

I don’t know much about this other than it’s darling and seems unique. Poly cotton blend. Vintage size 10 so I think it’s meant to be worn oversize. I would say it’s a modern medium or large. Please carefully review measurements. There is no stretch. Fabric is very lightweight. Approximate Flat Measurements Pit to Pit: 20” Length: 28.5” Waist: 20” Sleeve length: 17.5” sleeves are about 8.5” flat, very roomy
