SILK CARE INSTRUCTIONS: Dry cleaning or hand washing are the best methods for long-term silk care Despite common belief that silk can only be dry cleaned, hand washing or gentle machine washing is safe when done properly. If using a washing machine, we recommend placing items in a mesh washing bag to prevent scratching or pulling. For hand washing, please follow these instructions: Don't use harsh detergents containing bleaches or brighteners Use cold to lukewarm water and mild soap such as Ivory liquid soap or baby shampoo Add a few drops of hair conditioner to the final rinse for extra softness Never spray silk with perfume or deodorant Never bleach silk DRYING: Wrap silk in a dry towel, then lay flat Never wring dry Avoid direct sunlight exposure IRONING: Always iron the reverse side only Never treat stains with water or spray while ironing Use low heat setting STORAGE: Fold garment carefully To avoid center creasing, fold each side inward by a third"
