Pure Virgin Wool. Made in the USA! Vintage Pendleton brand, "warranted to be a Pendleton" likely 70s/80s, Size tag is illegible, faded to white. Pit to pit measured around 22", see photos. Sleeves are 21 inches from shoulder seem to wrist. Shoulders measure 17", front body length is just shy of 24 ". Some shrinking has occurred but the wool has retained shape. I'd size it as a women's Small or Medium. I wear a Medium 8/10 in jackets and it fits well in chest and shoulders without being too tight but the sleeves do clock a little short but absolutely wearable and can be cuffed anyway. I'm including a picture of myself in another size 8 jacket for reference. Please see photos of wear to hems of sleeves, just a little fuzzy, a tear on the right cuff. Features button-down, flap pockets on chest, plaid has bright red, cranberry and light gray/navy, pointed collar.
