ETERNA – MADE FOR EVERY VERSION OF YOU

There’s Power in Your Evolution. Strength in becoming you at every chapter of your life. In allowing your body to change, to grow, to soften, to strengthen and to honour it through every phase. Evolution isn’t something to resist; it’s something to embrace. With every shift, every curve, every new season, there is power in knowing you are still you; just deeper, wiser, more loved, more defined. And that power deserves to be celebrated.

For years San Lorenzo has been synonymous with confidence, comfort, and innovation. One-piece swimsuits crafted in fabrics that push boundaries to celebrate all female forms. Now, for the first time ever—and long awaited—we’ve brought our most beloved and iconic designs together into one cohesive story. A collection that honors every season of you, designed to evolve with you and celebrate every curve. 

Crafted to support, flatter, and celebrate you at every stage, it’s a collection that adapts as you do. Never chasing a certain shape or moment — it’s honoring the body you’re in right now. 

Your body will change over time, it will grow, soften, strengthen, curve, and evolve with every season of your life. And through it all, ETERNA is designed to move with you.  

Featuring three iconic one-piece designs, and a complementary two-piece ruched triangle set; each look comes with its own personality. Every piece in this signature collection was created to celebrate confident body movement with environment versatility, while staying true to the San Lorenzo legacy of flattering and inclusive swimwear. 

Meet ETERNA. San Lorenzo’s meticulously curated one-piece collection, fusing iconic design with modern allure. A stunning lineup of must-have one-piece swimsuits, reimagined like never before. 

The Essence of ETERNA 

ETÉRNA is a collection of philosophy; protection, comfort and fluidity.  Whether your body is athletic and toned, beautifully curvy, fuller through the hips, strong through the shoulders, or softly feminine in its lines, ETERNA embraces it. Designed to suit all body types, each silhouette enhances natural curves rather than reshaping them. The Triangle Thong elongates and highlights, the Retro Cut-Out defines and balances, and the Side Lace-Up allows you to adjust and contour your fit to celebrate your shape. 

MEET THE ICONS 

Triangle Thong One-Piece 
(One that celebrates every day, every curve) 
 
This beauty is a fan favorite, and it’s easy to see why. With a classic cut and subtle thong back, it complements even the fullest of bodies, fitting like second skin and supporting you gently and securely. Designed to double as the perfect everyday bodysuit, it gives you the freedom to move as if it were made just for you, with body confidence and love. It’s the kind of swimsuit that holds you with a soft, confident structure, from a beach sunrise swim to stand-up paddleboarding or kayaking to cooling down with rainbow-colored shaved ice. No visible lines, no awkward layering, just a seamless fit that slips effortlessly under all types of bottoms.  

Retro Cut-Out One-Piece  
(One that makes you feel beautifully put together) 

Step into the 90s supermodel era with our retro cut-out one-piece. Its high-waisted bottom and shell shaped  cut-out top capture vintage glamour, while thin spaghetti straps keep it delicate yet supportive. This piece is the fit for everybody —the kind that turns heads subtly in a local boutique shop, without ever needing to try too hard. It’s perfect for those dinners at a local restaurant, casual evening drinks, or nighttime walk along the boardwalk. 

Side Lace-Up One-Piece 
(One that understands your shape and never lets you down) 
 
Function meets YOUR BODY in EVERY CHAPTER is the side lace-up one-piece. Adjustable, flattering, and figure-enhancing, it allows you to customize your fit while celebrating your natural curves. The lace-up detailing is playful yet sophisticated, giving the swimsuit a modern edge. This piece proves that even the fullest body can be shaped beautifully, comfortably, and effortlessly, all while feeling bold and confident. The one that offers the most coverage. The one that supports you, smooths you, and holds you in all the right places. The one you reach for when you want to feel secure, sculpted, and confident again, especially when you need it most. 

Six essential color tones of True Pearl, Chocolate, True Crimson, Sunlit Meadow and Lush Olive anchor the line, chosen for their day-to-night ease and seasonless appeal. These colors transition effortlessly from surfing lessons, breakfast at a local café, to the farmers’ market or exploring a small town. ETERNA is the dream collection for SL babes to own her day without ever missing a moment. 

The One-Piece Advantage 

Bodies shift with age, movement, motherhood, training, rest, and life itself. Skin tone deepens in the sun, muscles strengthen, curves settle, and proportions change and that is the beauty of it. This collection is created to complement every tone, every curve, every phase. It supports where you need it, shapes where you want it, and flows with your body instead of restricting it.  

One-piece swimsuits are often underestimated. But they are often so much more than your two-piece. They’re about careless freedom, body confidence, and sun protection. At San Lorenzo, we’ve made sure that every piece embodies this. 

1. Freedom to Move 
   The ETERNA one-piece collection is designed for doing, not fixing your swimsuit. Run along the sand, dive into waves, or sprint into the surf without tugging straps or checking coverage. Every piece moves with you, allowing you to fully embrace the moment without distraction. Confidence is effortless when your swimsuit is fully in place, letting your body and mind feel free. 
2.  Confidence Comes From Feeling Secure 
   There’s power in a swimsuit that supports you, that lets you feel your best without constant adjustment. ETERNA provides that confidence naturally. When everything stays comfortably in place, you can focus on the experience around you. We want our SL babes to own their space and day, without worrying about exposure. 

Your body changes over your lifetime. And Eterna will be with you throughout it all.
