Nothing compares to the absolute luxury of pure silk pillowcases and sheets. And there’s a good reason for that: high-quality mulberry silk delivers many benefits, like preventing bedhead and tangles; minimizing sleep wrinkles; keeping hair and skin naturally hydrated; and regulating body temperature for maximum comfort in any conditions. On top of all that, the lustrous charmeuse weave looks and feels absolutely decadent. But silk is an investment—one you want to make last by treating it well.
