THE PERFECT ONE-PIECE

It is official, and the fashion press has said it out loud: the one-piece is the swimsuit of the summer. After years of the bikini, the single sculpted line of a one-piece is what editors are living in, for one simple reason. It does not stay at the beach. Pull linen trousers or a skirt over it and your swimsuit becomes a bodysuit, and the day carries from the sea to dinner without a change of clothes. We have been making swimsuits for exactly that life for years, here in Portugal, so allow us one confident line: these are, probably, the most perfect one-pieces in the world.

Coveteur called the one-piece "this season's biggest swim trend". CNN, Forbes and Marie Claire agree. We are not going to argue. We are going to show you the best one-piece swimsuits we make, drawn from three of our collections, and why the words made in Portugal on the label are the whole story.

Why the one-piece is the swimsuit of 2026

The appeal is practical before it is aesthetic. A one-piece swimsuit is the piece you do not have to think about. It holds you, it keeps its shape in the water, and the second you step off the sand it reads as a bodysuit under trousers or a wrap skirt. That is the beach-to-dinner move the whole season is built on, and it is why the one-piece, not the bikini, is the swimsuit editors reach for in 2026.

Swimwear made in Portugal

Here is the part that matters. Portugal is the small country where the world's luxury houses quietly produce. For decades its mills and ateliers have cut and sewn for the names you know from the front rows, which is exactly why so much of fashion sources here without ever saying so. Our swimsuits are made in Portugal, in that same tradition: the fabric has weight and recovery, the lining is real, the seams are finished to last a hundred swims. A swimsuit made in Portugal fits differently because it is built differently. That is not a slogan. It is the reason ours keep their shape long after others have given up for the summer.

How to choose a flattering one-piece

Four things make a flattering one-piece swimsuit. A cut that sculpts without squeezing. A fabric heavy enough to stay opaque and hold the body when wet. A neckline that flatters the face, whether it is a clean scoop or a deep plunge. And a leg line that lengthens. Get those right and a one-piece does something a bikini cannot: it gives you a single, uninterrupted line, which is the most elegant thing you can wear on a beach.

The best one-piece swimsuits, by collection

From À la Riviera, the Grace is the clean scoop and the Iconique and Monaco are the black ones you will live in. From Postcards from Positano, the Capri and the Ravello carry the colour of the Amalfi coast. And from the Salt & Sun Edition, the black Revenge, the plunging Royal Mansour and the white Ivory are cut for Portugal's Atlantic light. Every one of them made in Portugal.

The one-piece that doubles as a bodysuit

The finishing move is the same one the whole trend rests on. This is the one-piece that doubles as a bodysuit: step out of the sea, pull on trousers, add a warm line of golden jewellery, and the swimsuit is now the outfit. We wrote the full guide to that in From Beach to Dinner, and paired the swimwear with the right pieces in Salt & Sun Swimwear and The Côte d'Azur Swimsuit. The one-piece just makes it effortless.
