I purchased this at Uniqlo in Umeda, Osaka a few years ago and wore it once before cleaning it at home and storing it in the closet. Inseam is about 78cm. A family member bought it, but I'm not sure if it's dark navy or black. I apologize for the ambiguity. (._.) There are a few wrinkles from storage. I will compress it for shipping. Please purchase only if you understand and accept this.
