Six years ago I purchased a Mayle chain and leather waist belt and have been looking for similar ones for my clients ever since. (Still mourning the loss of Mayle)
Search over. This morning I found the Marc by Marc Jacobs Ruth belt and it is exactly what I was looking for and at half of the price of my Mayle version!
Wear this piece around the waist of your silk tops or as a necklace. All of the new chain Lanvin belts are dual purpose as well, so you will be ahead on this one.
