I had one MZ Wallace bag that I purchased several years ago. I got it on sale and would have been upset if I had paid full price because it didn't hold up as they are expensive.
It was a beautiful gray/ linen bag that had a coating on it to give it a gorgeous texture but after using it for two years (I mostly used it in the summer) it started to peel.
Unfortunately it got too bad and looked shabby so it's no longer in my bag collection.
