You know those holiday pieces that work harder than you do? The one-piece swimsuit is absolutely that. Not just for swimming—or sunlounging in the manner of a someone who’s just inherited a vineyard and absolutely no responsibilities—it’s the ultimate wear-it-your-way essential. It’s flattering. It’s fuss-free. It doubles as a top. It demands very little and gives very much.

Here, we’ve styled Valentino’s beautifully minimal suit three ways: poolside and practical, dressed-up and directional, and all-out Riviera romantic. Think loose tailoring, oversized sunglasses, woven accessories, and a dash of maximalist jewellery for evenings when you’re five per cent sunkissed, ninety-five per cent Negroni.

Whether you’re in the Med, the Cotswolds, or just playing holiday in your own garden, this is your summer starting point.

Proof that practical doesn’t mean boring. Throw on a striped men’s shirt, denim shorts and sandals that will go the distance, from beach to bookstore. A wide-brimmed hat and sleek shades = instant chic.

A one-piece—but make it fashion. Style yours with printed silk trousers, gold jewellery and mermaid-worthy earrings. Add a lightweight jacket for cool evenings—and a sense of mystery.

Retro, romantic and a little bit fabulous. A crisp white skirt, woven accessories, and a bold earring moment channel serious old-school holiday glamour—with none of the effort.
