Barberini black pea coat knee length coat

There’s no identifyingg tags in this coat so I have no ideas what it’s made of or the size. I do believe it was purchasedd from nordstroms 15-20 years ago. Armpit to armpit 19 inches (Collar) Top to bottom 41 inches was Under pocket to each side (I imagine one where hips would sit) buttoned, 20 inches Shoulder to bottom of sleeve 22 inches Bottom of sleeveve width flat nearly 6 inches Shoulder to shoulder from the hem at top of sleeve 16.5 inches If I was to guess I’d say a size 6. It’s very warm so it couldd possibly lay be a wool/cashmeree blend? Let me now if you have any questions, want more measurements. Union made tag inside. Barberini brand tag inside.
