The heritage of Silk, re-imagined for modern beauty rituals

Centuries ago, Mulberry silk was reserved for royalty. Today, By Dariia Day brings that same regal comfort to your nightly ritual - upgraded with strict sustainability certifications and modern testing.

Why 25 Momme & 6A Grade Matter and what it means for You?

25 Momme Density → long-lasting sheen & luxe drape
6A Grade Fibres → smoother surface that glides over skin & hair
Long-Strand Mulberry Natural elasticity → pillowcase keeps shape wash after wash

Quick science hit: Dermatologists confirm that less friction equals fewer sleep creases and reduced overnight moisture loss—key to glowing “Day Skin” at sunrise.

Triple Certification, zero compromise

OEKO-TEX® Standard 100 — independently tested for harmful substances.
GOTS organic textile — verifies eco-friendly mulberry cultivation and clean processing.
Reach compliance — meets the EU’s strict chemical-safety standards.

Translation for your beauty routine: pure silk against your face, free from toxins that could irritate sensitive skin or disrupt hormones—because wellness starts on the pillow.

Our silk begins its journey in certified organic mulberry orchards where silkworms feed on leaves cultivated without synthetic pesticides or fertilisers.

The raw silk is spun and woven in a vertically integrated, OEKO-TEX-audited mill to achieve our signature 25 momme charmeuse.

3. Hand-Sewn in Europe

Each piece is finished in our family atelier in Poland, and final quality check - luxury you can see and feel.

FAQs

Will a 25 momme pillowcase feel heavy on my face?

Not at all. Density refers to durability, not stiffness; the finish stays feather-light.

Is OEKO-TEX the same as organic?

OEKO-TEX certifies chemical safety; GOTS covers organic farming. We hold both.

Can I machine-wash it?

Yes—choose a delicate cycle, liquid detergent designed for silk in cold water, and our silk wash bag to maintain the weave.
