The color was AI-judged as dark gray, but it's quite a dark color, so some people might see it as navy. It's difficult to judge from the photos, and the color may appear differently to different people, so I cannot answer questions about the color. Please refrain from purchasing if you are sensitive to this. I've worn it many times, but there are no noticeable stains. No returns.
