Super soft, luxurious 100% cashmere cardigan sweater from Neiman Marcus in a navy/cream/heather grey colorblock pattern. Very gently worn, with no tips, snags, spots, or defects and no pilling. Size M but with a slim fit that’s better suited to a S or even XS. Measurements, as pictured: Chest approx 16” buttoned, unstretched Length shoulder to hem approx 24” Sleeve length approx 24” Ready to ship, from a smoke free home. I purchased at a resale shop but have never worn this; it’s possible it hasn’t ever been worn.
