Marni x Frank Navin multi-colored printed skirt

Black multicolour Marni x Frank Navin printed maxi skirt from Marni featuring a high waist, a flared style, a long length, a back zip fastening, a contrast piped trim and an all-over print. I could not find the size list on the skirt. 13 inches at the waist. Size 6 is a guess based on measurements. Tag is falling off as pictured.
