TNA Aritzia cozy fleece boyfriend boxy zip hoodie with flaw-discolouration

TNA cozy fleece boyfriend boxy zip (crop fit) hoodie with flaw-discolouration, purchased June 2023. Photos reflect discolouration present on front of the sweater, heavier on the right breast and shoulder. I’m not sure what happened, I think I tried to treat a spot with dawn power wash and the dye rubbed out. Has gone through the dryer, condition of the fleece inside pictured. I only wore this under a handful of times. Colour is sage frost. Matching sweatshorts available-there is a listing for the set in my closet!
