YSL preloved crossbody bag

I positively love this bag. If I didn't have so many bags, I would keep it. The outside pouch on the back and the inside of the bag are very clean. The only callout is in the last photo... a couple of spots on the bottom of the strap where it attaches to the bag. They may be able to be cleaned? I'm not sure. The strap drop is 21" at its shortest and 23" at its longest.
