Neiman Marcus cashmere cardigan, '60s-'70s from Hong Kong

This black, button-front, double-pocket, 100% cashmere cardigan from Newman Marcus has an older label: "NM Only, a Neiman Marcus Exclusive" and a tag that shows it was made in Hong Kong, confirming it's from the '60s or '70s. It's a size L, doesn't have any holes or stains, but as an older sweater, it shows more pilling, and the shell-like material of which the buttons are made have damaged fronts, with the bottom button missing part of its top (see photo). I had a second NM sweater which I felt was too shapeless to sell, so I cut off its buttons and am including them with this sweater for a buyer to sew on if they are so inclined. The listing price reflects the issues with this sweater. All clothes offered in this account belonged to myself or a family member, so all single owners and nonsmokers. Most items are from the '70s to the 90's, although some will be from earlier decades. They've been stored in a closet and dressers in a third bedroom, but it's time for me to downsize, so I am selling the collection. I'm starting with sweaters, but will also list premium-brand jackets, coats, pants, skirts, dresses, blouses, scarves, and other accessories. Note: My older relatives were clotheshorses; I am not, so please consider the photos the main descriptive elements as clothing terms are generally unknown to me. I'm happy to answer any questions you have if I can!
