Mono Bikini, Ocean Blue
Incl. VAT, plus shipping
This is the HACOY mono bikini in Ocean Blue. This is not just swimwear. This is a reflection of the environment it was made for. We have engineered this piece from a brutal, honest principle: true beauty lies in harmony with nature, and sometimes, less is everything.
A Synthesis of Calm and Confidence
The ocean demands respect, and your attire should mirror its depth. This garment is designed to embody that spirit. Our Mono Bikini is a synthesis of a calming, single-tone hue and a minimalist design that prioritizes natural shape.
- The Ocean Hue: The soft, single-tone Ocean Blue brings a calm yet confident vibe to your beach look. It is a color selected to resonate with sun-soaked days and the clarity of water.
- Custom Silhouette: Hardware-tipped adjustable ties on both the top and bottom allow you to sculpt the fit perfectly to your body. The triangle top mirrors the minimalist aesthetic while offering versatile styling options.
- High Cut Leg: The bottom is engineered to sit high on the hips, elongating the legs and framing your natural shape for a flattering, timeless silhouette.
Emotional Durability for the Water
We make swimwear for many summers. Your connection to the water should be supported by quality. The HACOY mono bikini is cut and sewn near Ferrara, Italy, by a small house of highly trained seamstresses.
- Italian Softness: Made from premium Lycra (80% Polyamide, 20% Elastane), it feels like a second skin, soft against the body and resilient against the elements.
- Made near Ferrara: Cut and sewn by a small Italian atelier.
