What this climate and context demand

Changeable conditions reward layering over single heavy pieces, since you can add or shed warmth as temperatures drift through the day. Mid-weight wool and wool blends offer the best balance here: high warmth-to-weight, strong wrinkle recovery, and the ability to stay comfortable when air sits cool, mild, and saturated by turns.

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 — Drying speed matters most in this climate, because persistent humidity keeps slow-drying fibres feeling damp and cold against the skin long after exposure.
