Vintage 1960's Playmaker by Mannie Fineman Paisley Shirt Retro Groovy

Groovy vintage 1960's Playmaker by Mannie Fineman California paisley/psychedelic button down shirt. I suspect this is a men's shirt but could definitely be worn unisex. No size listed but fits like a small (does not fit me which is why it is pictured with buttons left open- I am a size M/L.) Due to the secondhand nature of this item, there are some slight signs of wear like discoloration but is otherwise in great vintage condition! 20" from pit to pit when laid flat, 15.5" from shoulder seam to
