Vintage 60s/70s Designers Dayfarer Polyester Tee

Super awesome and unique Dacron polyester short sleeve top from Designers Dayfarer! Vintage from the 60s or 70s. Blue with red and white stripes. I do not see a size anywhere, but I’d say this fits a small/medium. (I wear an XS and the top fits a little loosely.) Bust measures about 18in, length 24.5in. Fabric is super stretchy. In excellent vintage condition with no flaws to note! Offers considered :)
