Vintage Abercrombie Crochet Cardigan Sweater

I bought this at a yard sale about 15 years ago. It’s been gently used. Some of the flaws it has are scuffing at the buttons and one of them has cracked. It also has a bit of pilling throughout. The buttons are made of wood It says size large but it must have shrank at some point because it fits me perfectly and I’m an XXS. I can provide measurements upon request.
