I purchased this at a pop-up event held in Ikejiri. I've only worn it once, and it's been stored in my closet after being cleaned. I'm selling it now as part of a decluttering effort. Please feel free to ask any questions you may have. Thank you for your consideration. Brand: Cornier HARD TWISTED COTTON WORKING SHIRTS Color: Charcoal Size: L This work shirt is made of a plain-woven, super-twisted cotton material. During the yarn twisting process, a special twisting technique is used to maximize the number of twists, resulting in a material that, despite being cotton, has a rough texture and a strong stiffness similar to nylon.
