What this climate and context demand

A Mediterranean climate rewards breathable, open-weave fibres in summer, when low ambient humidity lets perspiration evaporate and cool the skin efficiently. Linen and cotton, with high air permeability and strong moisture absorbency, shed dry heat far better than synthetics, which trap warmth and hold odour against the body.

Business casual sits between suiting and weekend wear, so fabrics should hold a crease without stiffness: mid-weight cotton twill, fine merino knits, and wool blends with some elastane recover from sitting and movement while keeping a clean line.

Fabric priority — Air permeability matters most, because dry summer heat is best managed by fabrics that let evaporated sweat escape and air circulate freely against the skin.
