Vintage 1980's bowling shirt or blouse

Vintage 1980's bowling shirt/blouse. Such a cool piece, I thrifted it a couple years ago and just haven't worn it much so I figured it's time for it to find a new home. In really good condition aside from a few stains on the front (pictured). I'm sure they could be taken out easily but I am not too familiar with vintage clothing care and was too afraid to try😅. Oversized design with a cinched waist band at the bottom. Buttons come all the way undone but the waist band holds it closed. No size tag but I'd say it fits a current standard size medium pretty well, could probably also do small or large depending on the fit you want. Feel free to ask any questions or send an offer:)
