The Inspiration: Your most precious accessory as… your most precious accessory. I saw this Chanel 2.55 bag kiddie costume on Pinterest, as did thousands of others who promptly re-pinned it. Equally as amazing and adorable is the most coveted bag of all: The Hermes Birkin–on an adorable child.

The Formula: No idea. But the original crafty blogger who created these costumes is here.
