J.Crew Cashmere crewneck slim fit sweater blue size small

I have this sweater which is a really pretty blue. Unfortunately it’s had some wear, it was worn on a movie set and there were some dirt marks. I cleaned the sweater gently and it appeared to be good, but I can see faintly some discolouration. As well as a small area of wear. I hate to throw out cashmere so I’m hoping to sell to someone who would like to refurbish it. It can be washed gently in cold water Size small
