Banana Public-M-gray-extra fine Italian Moreno wool turtleneck, pullover sweater. 88% Moreno, extra fine wool, 10% nylon, 2% spandex. Capsule wardrobe piece. Looks like it’s been sewn in two places one on the back near seem, one in the front. see last 2 photos (one upfront you can’t even see it). See photos for approximate flat measurements. Seems like it would be a small instead of a medium.
