Tróia, Portugal. A slender ribbon of sand where the raw power of the Atlantic meets the calm shimmer of the Sado estuary. Long, empty beaches stretch out under vast skies. Dunes roll gently into pine forests scented with warm resin. And, if you watch for long enough, you might even see a dolphin surface in the glassy river shallows. The evening light hits different here, which is part of the reason ISTO chose it as the location for its latest lookbook.

Highlighting new pieces from the brand's summer 2025 range, this carefully curated collection of golden-hued images acts as a handy guide book for nailing laid-back summer-evening style. Gently rumpled linen shirts rub shoulders with olive-green tailoring, while the odd sun-bleached baseball cap ensures things never get too stiff.

It's a masterclass in colour matching too. All-white tonal ensembles are counterbalanced by high-contrast combinations. A brown linen shirt in brown with breezy blue linen shorts, or an unstructured khaki blazer worn loosely over a pale blue shirt. If you're summer style is stuck in a rut, there's plenty to be gleaned from ISTO here.

The key to the easy feel of the styling lies in the fact that these are pieces immune to the passing of trends. They're timeless summer staples, subtly tweaked and refined to make them the best they can be. They look great now. And they will look great another 20 years from now too. Whether you're collecting driftwood on the beaches of Tróia or navigating the high-summer heat in London.
