Care Instructions
Care Instructions
When it comes to washing silk underwear, it's important to take extra care to avoid damaging the delicate fabric.
We recommend hand-washing in cool water with a gentle detergent specifically designed for silk. Gently agitate the garment in the water for a few minutes, then rinse thoroughly in cool water. Avoid wringing or twisting the fabric, as this can cause stretching or damage. Instead, gently press the water out of the garment and lay it flat to dry on a clean towel.
Avoid direct sunlight and heat, which can cause fading or shrinkage. With proper care, your silk underwear will stay soft, luxurious, and beautiful for years to come.

This is intimate luxury designed for daily performance.

Care Guide
Silk is a protein fibre, like hair, so treat it gently. Hand wash cold with a mild silk detergent, or use the silk cycle at 30 °C. Turn inside out and wash separately from other colours. Do not wring, no bleach and no fabric softener. Roll in a towel to remove water, then dry flat in shade. Do not tumble dry.
FAQ

- Will they make me sweat? No, quite the opposite. Silk is the most breathable natural fiber, reducing sweat and managing moisture better than cotton.
- How does the sizing run? True to size. If you prefer a looser feel, for sleeping, size up.
