Crepe silk can indeed be pure silk. Crepe refers to the fabric's distinctive texture, defined by its crinkled, crimped appearance.
When made from pure silk fibers, it is referred to as "pure crepe silk." However, crepe fabric can also be produced from other fibers
such as polyester or rayon, which mimic the texture of silk but are not genuine silk.
Therefore, it's essential to verify the material composition and source to ensure you are getting authentic pure crepe silk.
