100% cotton pique knit polo XL Orange

Pit to pit 24 inches 31 inches long Was washed, hung up in the closet and never worn. But it looks like something dark bled a little bit of color into the middle upper back of the shirt. There’s a little bit of dark shading there like something dark leaked a little bit of color in the wash. I don’t see any stain anywhere else on the shirt. It’s otherwise in perfect, the cats are bullying never-worn condition. Non-smoking home .
