NWOT Pink Lily Blue Plaid Shacket

Bought this on final sale and unable to return it as it's too small for me. I'd say it runs on the smaller side as I usually wear a size medium in tshirts. It's brand new and never worn. Posted on here immediately after I received it in the mail and tried it on; no tags were attached. Button front with double pockets, unlined. 25 inch p2p and 26.5 inches long.
