Vintage PENDLETON Virgin Wool Red Sweater Vest Size 40 fits like a small to med

Pendleton 100% virgin wool Size 40 fits like a S/M I have a large chest which makes me not like the fit so much. Beautiful cable knit vintage sweater vest. Free of holes and tears. One button has a small line of red missing see last photo. There is also a close up picture of above the button hole that could be a stain or somehow a darker spot. I washed and spot cleaned the area and it did not change. It is not noticeable on but in certain light angles I think I see it. Could be how the wool was dyed. Anyway it is still very much wearable and looks in great condition for the age. It is a beautiful brick red color perfect for fall. Length: 21 Width: 18 Measurements are approximate. Length is measure from the top by the neck to the bottom.
