It always excites me every time Chanel launches its new costume jewelry collection. For their Pre-fall 2015 the collection is called Métiers d’Art (Craftsmanship). Karl Lagerfeld the ever famous creative director of the house of Chanel incorporated the work of the famous European artisans and Austrian Imperial.
Velvet, gemstones, pearls... When you see the collection, it's like you are hearing the famous waltz by Strauss and Mozart.
Of course Chanel is known for classic pieces, but I find Métiers d’Art Collection -- Extravagant!
