Color: Navy系 (Navy-based) Collar/Neck: Regular collar Transparency: None Season: Autumn/Winter Stains, tears, odors, etc.: None This is a classic flannel shirt. I think it's a convenient piece that can be worn on its own, as an outer layer, or layered under a sweater or sweatshirt. I think I washed it at home and wore it once, then stored it in the closet. I would appreciate it if you could understand that it is used.
