Green COS asymmetrical cotton linen top

This top is like if a wood nymph meets modern fashion. A lovely sage green and the fabric of the top feels very premium and hangs well. Asymmetrical sleeves - right one is a big sleeve, left is sleeveless with a tie top and buttons that snap together on the side. There's one spot of discoloration by the armpit of the right sleeve. I didn't notice it for a while because it gets tucked into the folds that the big sleeve creates but you can see it when you hold the fabric straight out.
