What should you wear in humid weather?
Loose, light-colored linen or open-weave cotton. Fit and airflow matter more than fiber - nothing should touch more skin than necessary.
Humidity defeats evaporation, which is how sweat cools you - so the strategy shifts from absorption to airflow. Loose fits win: a shirt that floats off the skin lets air circulate; a fitted one becomes a damp second skin. Linen is the best fiber because its open weave breathes and it absorbs moisture without feeling clammy. Light colors reflect heat. Specific moves that help: unlined and unstructured jackets if a layer is mandatory (lining is a plastic bag in disguise), cropped or wide-leg pants over skin-tight anything, and natural fiber underwear (synthetic in humidity is misery). Carry the blot, not the wardrobe change: a handkerchief and a midday shirt swap in a bag beat suffering through.
