A refined statement of minimal luxury, this white swimsuit is designed to sculpt and elevate the silhouette with effortless elegance. Featuring a deep plunge neckline, it is defined by a striking gold shell detail at the center, adding a bold, sculptural focal point inspired by Mediterranean treasures.
The clean lines and smooth, structured fabric create a sleek, second-skin fit that enhances the body while maintaining a sophisticated, timeless aesthetic. Its high-cut leg elongates the figure, while the halter neckline provides both support and a flattering frame to the shoulders.
Understated yet powerful, this piece is the perfect balance between simplicity and statement—designed for women who embody quiet confidence and refined sensuality.
How to style:
Pair it with a flowing pareo or linen trousers for a chic beach club look, or elevate it with gold jewelry and oversized sunglasses for a polished resort aesthetic. Add leather sandals or heels for a seamless transition from day to sunset.
Fit:
Sculpting fit with a halter neckline for support. True to size

FAQ
Who is behind the Archivio Atti universe?
Our designer, Sandra, creates each piece out of a deep obsession with silhouette, movement, and memories of the Mediterranean light. Her partner, Pablo, meticulously shapes the evocative atmosphere that define the world Archivio Atti lives in.
How do your pieces fit?
Our pieces are designed to be intuitive, effortlessly falling and feeling right without a second thought. Their fluid silhouettes transition seamlessly from a street at golden hour to a quiet evening gathering.
What defines your quality?
We are obsessed with clean, natural fabrics that carry a strong sensory presence against the body. Each piece is crafted as an intentional gesture of strength and femininity made to outlast transient trends.
What inspires your collections?
Each collection is inspired by memories like linen drying in the sun, a half-open window, or salt on the skin. We weave these moments into the garments so they carry an invisible story before joining yours.
Are your designs age-inclusive?
Embracing the spirit of Isotta degli Atti, our silhouettes celebrate a timeless presence and a quiet elegance that never shouts for attention. Every piece is designed to honor and elevate femininity through all stages of life.
What are shipping times?
After a 24–48h hand-preparation ritual in Spain, tracked UPS shipping is free worldwide. Delivery takes 24h within Spain, 48–72h across Europe, and 5–8 business days for international destinations.
What is your return policy?
To ensure complete peace of mind, standard orders can be returned within 14 days of delivery if unworn and in original packaging. Once approved, your refund will be issued to your original payment method.
Can I modify or cancel my order?
Modifications are gladly accepted before our dedicated hand-preparation ritual begins in Spain, but cancellations are not possible once an order is in preparation or contains a presale item. However, provided the items are eligible for return, you can absolutely request a standard return within 14 days of delivery.
How are customs handled?
Local authorities determine customs duties outside the EU, and they are handled independently by the client upon arrival. For international returns, please note that any incurred customs fees or tariffs will be deducted directly from your final refund.
