Necklines That Do the Work: Sweetheart & Bustier One Pieces Worth Knowing

There is a reason the sweetheart neckline has endured across decades of fashion — it frames the décolletage with an architectural precision that few other cuts can match. Translated into swimwear, that same logic holds. A well-constructed bustier or underwire one piece does more than look polished at the pool; it offers the kind of structured support and intentional shaping that makes a swimsuit feel as considered as any piece in your wardrobe.

This season at Lola Dré, the sweetheart one piece gets a full editorial treatment — from understated stripe work and seersucker textures to hand-placed floral prints and silk-touched fabrications. Here, structure and beauty are not at odds. They are the point.

Montce Swim's Bella in Seafoam is where to start if you want the bustier silhouette in its most wearable form. Cut from a smooth, chlorine-resistant fabric with boning at the cups and a sweetheart edge, it sits cleanly on the chest without needing adjusting throughout the day — the kind of detail you only appreciate once you've worn a poorly constructed alternative. The soft seafoam tone reads equally well against warm tans and fair skin, making it a quietly versatile choice for resort travel.

At the other end of the spectrum, Dolce & Gabbana's Celeste Floral Bustier One Piece is unmistakably Italian in its sensibility — bold botanical print, structured boning, and strappy back detailing that references the Maison's signature Mediterranean flair. It's the kind of piece that earns its price point through the precision of its construction and the weight of its fabrication.

Pattern Play: Stripes, Plaid & Seersucker

For those who prefer their swimwear with a graphic edge, both SIMKHAI and Solid & Striped are working in interesting territory this season. SIMKHAI's Noa Lobster Stripe Belted Bustier One Piece pairs a sweetheart neckline with a removable belt — a small but meaningful detail that gives the piece definition at the waist and transitions it effortlessly from water to a poolside lunch. The lobster stripe print nods to classic nautical references while the belted waist keeps the silhouette thoroughly modern.

Solid & Striped brings two readings of their Taylor silhouette — a plaid seersucker version in multi and a noir plaid underwire style. The seersucker fabrication is a particularly thoughtful choice for swimwear: the textured, puckered weave is lightweight and fast-drying, making it as practical as it is visually interesting. The noir colourway, meanwhile, leans into a more tailored, almost suiting-adjacent aesthetic — a one piece that could just as convincingly be worn as a bodysuit under wide-leg trousers for a summer evening.

Camilla: Print as Craft

No conversation about luxury one pieces is complete without Camilla. The Australian label has spent two decades building a reputation for richly pigmented, narrative-led prints — each one hand-drawn and developed in-house before being applied to their swimwear via a digital printing process that preserves the depth and detail of the original artwork. Both pieces here feature moulded underwire cups — a construction method that eliminates the need for removable padding and gives a cleaner, more enduring shape wash after wash.

The Livin La Vida Rosa features ruched cup detailing that adds texture to the bust, while the Ceramic Panoramic takes a cooler direction — a white and blue print that evokes hand-painted Portuguese tilework, perfectly suited to a Mediterranean itinerary or a sun-drenched rooftop.

What unites every piece in this edit is a shared commitment to the idea that a swimsuit can be as intentionally crafted as any garment in your wardrobe. At Lola Dré, that's precisely the standard we curate to.
