Zara light blue Mid-rise distressed Skinny jean size 4

Zara distressed light blue Mid-rise Skinny jean. The jean is in great condition and fits like a jegging. There are not tears or faults with the jean except for the tiny stain at the back of one of the legs, as can be seen in the photo. I have not tried to remove the stain but maybe you can. The size of the jean is a size 4 short.
