Material: Cotton This is a cool, thin cotton fabric. It has a wax-resist dye (rouketsu-zome) style. It's from about 20 years ago, so it's close to vintage (I previously listed a dress made of the same fabric). It also has a back lining, and although it's an Aloha shirt, the tailoring is solid. This is a worn item. There is some wear and tear typical of indigo dyeing. There is also some wear on the collar (see photo 8). There is no discoloration on the sleeve caps. I have examined it and found no other tears or stains, but it is a worn item. Please refrain from purchasing if you are concerned about this.
