Rag & Bone Silk Blouse Size M *Flaw*

Rag & Bone Button Down Blouse 100% Silk Size Medium Geometric print Made in USA pit to pit measurement- approx 18.5" There is a small stain on the back of the sleeve near the elbow. I tried to remove the stain, but it is still visible. The area around the stain is a bit lighter due to the stain remover. Please see the last 3 photos for reference.
