NWT KILLSTAR 4X Black sweats/leggings

These are listed as a 4X but they seem smaller than that. I am assuming with the stretch in them they would most likely fit a 4X. By the measurements I believe a 2X to 4X could fit these. The are 20" across the waist laid flat and the inseam is 31" Material is 95% cotton and 5% spandex. Very soft, comfy leggings/sweats. WPSP167L02Grp101625
