New without tags Dee Elly XL Marianne cream and sage waffle knit top

New, never worn, Dee Elly Marianne cream and sage waffle knit top/lightweight sweater in a size XL. V-neck collar with 3/4 length sleeves. Purchased from Stitch Fix and put into my closet. When I removed from my closet I noticed two discolorations on the front (see photos), not sure if those were there when I purchased it or if it occurred in my closet. Comes from a pet and smoke free environment.
