Parrish LA Wool Cashmere Cardigan Sweater Thick

Appears new--not seeing any signs of wear on this cozy wool/cashmere sweater. Normally, the underarms and inside cuffs will start to show wear and pilling first and those two areas are immaculate. This sweater is thick and has a bit of springy squish to it due to the wool and 10% polyamide. Sleeves are full-length. I don't know what's up with the piece of red yarn at the back collar. It looks intentional and doesn't seem to be holding anything in (like the inner tag). Stitching goes about an inch and a half. Would be very easy to remove without damaging the sweater using a seam ripper or fine point scissors.
