I cant really speak for the Diorever or the metallic leather but my experience so far with Dior products (i.e. lambskin) has been fantastic. I love that when the lambskin gets scratched, you can easily buff it out with leather lotion. People think the Lady Dior in lambskin is very delicate but it actually is not "that" delicate. It's a very solid bag. All my other purchases are really well made as well. Plus, I have to say that the experience at Dior boutiques is truly what luxury should be. In my opinion, because they're so popular, Chanel
Gucci Hermes etc. they're not truly luxury anymore. You go in, you ask for an item, you pay and leave. But at Dior, you make conversions, the SAs show you other products, educate you about the brand, they go out of their ways to help you. I always come back from a Dior boutique with an over the moon feeling. To me, that is what luxury should be, and so far in my own experience, only Dior (and sometimes Louis Vuitton) can deliver.
The Lady Dior is my favourite design and I'm definitely adding a few more to my collection in the future!
