Crochet free people sweater/pool cover up

Like new free people sweater / pool cover-up. I bought this as a sweater but could never stylet correctly for me. My sister wore it to the beach once this summer as a cover-up and it was super cute could definitely be styled either way. No unintentional holes. No stains or rips. Color is like a purpley gray. Would suggest it as a true L to someone looking to wear it as a sweater, or as a S or M if looking to wear it as a cover up.
