Chico's Travelers charcoal gray wide-leg pocket pants

Chico's Travelers wide leg pocket pants in Lavastone, which is a charcoal gray color. Size is marked as a 0, which is equivalent to a size 4. However, I believe it's mis-marked as the measurements are larger than my other Travelers pants. The measurements correspond to a size 1 or 1.5, which is an 8 to 10 size. Waist measures 16 in across, rise is 13 in, and length is 29 in. Fabric is acetate, nylon, and spandex. machine wash and dry, easy care. new, never worn.
