I don't have a tag, but I think it's Toropicana. A web search turns up a shirt with the exact same pattern. I've included it at the end of the images. It's well-made and can be worn without being see-through. Dry cleaned. Worn once. No stains. It was a souvenir from a relative who loves to travel abroad. I think it was probably a souvenir from Hawaii or America. It's a vintage Hawaiian Aloha shirt, and I think it's rare. It's a loose Japanese men's size M to a regular L.
