This is the HACOY luxury silk slip. This is not lingerie. This is a second skin forged from the principles of Quiet Luxury. This is our answer to a brutal honest question: Why must a woman choose between comfort and elegance?
A Synthesis of Sensation and Structure
The modern wardrobe requires foundations that are as considered as the outer layers. This garment is designed to be invisible to the world but essential to the wearer. Our Luxury Silk Slip is a synthesis of sensory pleasure and architectural fit.
- Intelligent Fabric: Crafted from the finest quality pure silk with a touch of elastane (4%) for movement. It is not just soft; it is intelligent—a natural breathable fiber that regulates temperature and moves with you.
- Invisible Fit: The cut is a ruthless exercise in minimalist perfection. Engineered to provide a seamless invisible fit under any garment it acts as a silent testament to superior design allowing your dresses and skirts to drape perfectly.
- Daily Luxury: This is not a garment for special occasions. It is a foundational piece engineered for the simple daily pleasure of feeling perfectly at ease in your own body.
Emotional Durability for the Self
We reject the premise of uncomfortable shapewear. Your confidence comes from within not from constriction. The HACOY silk slip is ethically manufactured in Italy by a small house of highly trained patternmakers.
- Italian Artistry: Produced with the same integrity as our outerwear ensuring that the seams are strong and the finish is flawless.
- Quiet Confidence: This is the essence of Comfortable Elegance. A choice for a garment designed not for the gaze of others but for your own inner sense of well being.
Explore this foundational piece and discover a more intentional approach to your base layer. This is not about shaping your body. It is about honoring it.

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.

The Architecture
This is not lingerie; it is a foundational tool for a more intentional wardrobe. We engineered the piece with a bias cut, allowing the silk to drape and move with the body without clinging or twisting. The neckline and straps are refined to be discreet yet durable. Every seam is meticulously finished to lie flat against the skin, ensuring its role as a perfect, undetectable base layer for dresses, skirts, or even loungewear.

FAQ
- Will it cling to my clothes? No. The natural properties of the silk and the bias-cut design help it drape smoothly, preventing static cling that is common with synthetic slips.
- Is it see-through? The high-grade silk we use offers excellent opacity. The Ivory color may be semi-sheer in direct light, while the darker colors are fully opaque.
- Can it be worn on its own? While designed as a base layer, its elegant cut and quality finish make it suitable for lounging or as sleepwear.
