What is Raw Denim? Denim that has not been pre-washed, pre-faded, or treated.
Raw denim is denim sold in its original, untreated state. The fabric is dark, stiff, and rigid at purchase. Over months of wear, it softens, fades, and develops creases that follow the wearer's body. Raw denim is typically washed infrequently (every 6-12 months) to preserve the fade patterns. The opposite is washed denim, which has been pre-treated for softness and consistent appearance.
