French artisanal label Bleu De Cocagne utilizes one of the oldest dyeing techniques in the world to create the signature blue hue that runs through their entire collection. Cocagne, a ball of woad leaves, is boiled to produce the dye in which every garment is dipped a minimum of six times. This revived ancient application is applied to flowy kimonos and scarf-necked jackets constructed in premium linens and wools, which when washed, undergo an even further enhancement in color.
