Torrid beach cover or Pyjamas

This is a size 2x by the tag. It wasn’t worn but it was washed to try to shrink it. I’d say It’s more like a 1x. This could be a bathing suit cover up or lounge Pajamas. It could even be worn as a shirt and nobody would notice. It is Rayon/polyester. Back photo shows pleat down the back. like new - no tags
