Zara maxi skirt

NWT Zara maxi skirt. Size small. Is a solid ivory color. So cute with a blazer! Has a small spot on the bottom back of the skirt, looks like it may have fallen on the floor in the store. I have not tried to get the spot off but it did lighten up when I scratched it with my finger, so I think it’s probably dust/dirt and can be wiped off.
