Finding summer trousers that feel lightweight without becoming too pale can be surprisingly difficult for cool-toned colour palettes, which is why this rich navy works so well for Cool Summer, Cool Winter and Deep Winter wardrobes. The softened linen-blend texture keeps the colour approachable and easy to wear during warmer weather, while the deeper navy still gives enough contrast to flatter cooler colouring. Styled with white shirts, monochrome separates or softer blue tones, trousers like this create the kind of relaxed but refined outfits that cooler palettes often do best.
