COS wool colorblock cardigan

COS colorblock cardigan. Size S. Bought thrifted. There are two pale pink stains, one at the back and one near the right armpit. See photos. I have carefully hand washed and reshaped it as it looked like it had been in the washer and dryer 😞. The stains didn’t come off. I didn’t try with a stain remover. Smoke free home
