Poetry Drawstring linen pants light tan with pinstripe pattern -Size 12

Poetry Drawstring linen pants Size 12, length is 29 inches Drawstring waist Light pin stripe pattern- please note there are a few splotches as shown in the picture. I cannot tell if these are stains or part of the design as most of the pinstripes have little bubbles coming off them. There is a spot at the bottom rear hem of a pant leg plus the two around the knee area.
