This is a true Vintage SACHI of Hawaii. casual button-down shirt. Very Uncommon and hard to find. Despite being old and size tag faded away, the print is a rich brown and orange tone. This shirt's unique pattern, inspired by ethnic motifs, Polynesian? Thinking 1960s to 1970s. Size small to medium for men's would be a good estimate on the size. Fabric seems to be a cotton polyester mix, very bright and textured. There is so flaws on the shirt. - There's seems to be possibly a ink stain on the chest but it's around a black shell. See second to last photo. - Wear around buttons. Need repairs. See last photo.
