Vintage red wool mock neck sweater

Beautiful bright red wool blend sweater. Original vintage, very retro/pin-up girl style. Round red pear buttons but I’ve never buttoned it up, the holes are not obvious and I didn’t want to rip it. There is a small hole at the shoulder seam as shown. Appears mendable. There is some stretch but I would call this more of an XS than a small, feels like vintage sizing, pls see measurements.
