Vintage tweed dark and pale pink knit boxy sweater

Vintage tweed dark and pale pink knit boxy sweater Appears to have a light halo of yarn and perhaps a touch of felting hard to tell. No tags but appearance indicates it’s wool. The front of the neck is buttoned and the back has some imperfections in the knit but not super noticeable. The sleeves are also wide to go with boxy fit of design. 20 inches long by 20 inches pit to pit. No tag but I’d say size medium a bit oversized or large more fitted.
