Wildfox seeing stars sweater S

Oversized shown on sz 8 mannequin. Says dry clean only it is delicate but can be machine washed in bag and laid flat to dry. I bought this at a consignment store and there was a hole on the back I thought it was supposed to be like that because it is distressed but now looking at pics to post I’ve seen there is no hole on the back. No other issues to report.
