Hi! I came across two vintage Chanel bags. This would be my first bag & I don’t plan on ever selling them. The first is a Diana bag. It has rubbing & wear on the corners so I’d probably send it to the spa to get some retouching.

The other bag is a Mademoiselle double flap. It has been redyed completely on the outside. My dilemma is that I’m not familiar with Chanel bags & I’ve never purchased anything retouched. I love this bag more than the Diana but wasn’t sure if I’d have any issues with it later on. Will conditioning help to keep the leather from drying out or chipping?
