NWT Urban Renewal Dickies 874 Original Fit Work Pant Size L (Read description)

NWT Urban Renewal Dickies 874 Original Fit Work Pant Size L. These pants seem to have a strange fit. I am not sure why there is another button on the front, as I have never seen pants designed like this. The pants also have some fading or perhaps dirt that can be washed off on the right side (seen in picture 2). Please refer to the pictures/measurements, and let me know if you have any questions!:) Measurements: Waist - 18 in Hip - 20 in Rise - 12 in Inseam - 29 in
