Vintage Plaid Tunic Top

Vintage Plaid Tunic Top. Bold purple and blue flannel print. 3 functional buttons down the front. Rolled sleeves with decorative buttons. Got this at a secondhand shop selling it as a size Small but the oversized boxy fit could easily fit a Medium. 21" flat pit to pit, 25" shoulder to hem, waist of shirt tapers from the bust to an eventual 22". No fabric tag but it feels super soft and likely is mostly cotton. Love this piece but don't reach for it as much anymore, hoping it can find a new home where it will be shown off like it deserves. Vintage wear as pictured but no obvious flaws.
