Pure Collection 100% Cashmere Sweater

Gently used, 100% cashmere sweater from Pure Collection. Pink in color, US size 6 - theres a small dirt stain on the elbow, this was a hand-me-down gifted to me, I have not attempted to wash it out but it looks like it could be cleaned. I dont know how to clean cashmere nor do I want to ruin the sweater! Price reflects the stain
