To wear this cashmere sweater, you can simply put it on over a t - shirt or by itself. For a weekend look, pair it with tailored pants and flats as mentioned. When it comes to maintenance, always follow the care label. Generally, cashmere should be hand - washed in cool water with a gentle detergent. Avoid wringing it out; instead, gently press out the excess water. Lay it flat to dry to keep its shape. Also, store it in a cool, dry place, preferably in a breathable garment bag to prevent moths and keep it in great condition.
