Melange is a material and color series made of 100% silk on the inside that touches the skin and 100% organic cotton on the outside. Melange is a French word that means "to mix." The inner silk is woven with a luxurious pile of silk yarn in all colors, which absorbs and releases moisture from the soles of your feet. Even though it has a two-layer structure, it is made of one piece of fabric, so it does not shift around each other, and it is just the right thickness so you can wear it all year round. (This is the organic cotton version of "Material and Color MIX") The combination of silk and organic cotton colors creates an expressive and unique color. I hope you find your favorite color.
