The Theoria item has the bottom button missing. It's a light blue? gray? kind of color. It shows signs of wear, but I don't think there are any noticeable stains. When I used to wear it for work, it didn't agree with my skin, so I cut off the tag that was on the side, so I don't know the exact size. If you are a Shimamura customer, please check with your size 15 item to confirm.
