Ralph Lauren 90% wool 10% cashmere grey sweater extra small

Authentic Ralph Lauren wool+cashmere sweater It’s a size medium but I’ve accidentally washed it in washer and it shrunk quite a bit so now it fits an extra small. The measurements are as shown in pictures. Pit to pit: 15.5” Top to bottom: 19” Sleeve length: 18.5” There is some minor piling because it’s wool and wool sweaters naturally pile. They are easy to remove. I bought it for $288 plus taxes online, now asking for $100
