Will I ruin my suit in the humidity?

Not if you keep it off your skin. Use the hotel steamer daily to release fibers that have become damp; this prevents mold and persistent odors.

Can I wear open-toed shoes for business?

In most professional settings in the tropics, closed-toe shoes are still expected. Opt for unlined leather loafers that offer ventilation.

Keeping It Professional in Tropical Heat

To stay professional in the tropics, prioritize natural, breathable fabrics like linen blends, merino wool, or seersucker. Focus on a 'base and layer' system that allows you to shed heavy outer pieces while maintaining a polished silhouette in air-conditioned interiors.

Select the right fabrics. Avoid synthetics like polyester, which trap sweat. Choose high-twist tropical wool, linen-cotton blends, or cupro. These materials wick moisture and dry significantly faster if you get caught in a sudden downpour.
Use a garment bag for structured pieces. If you must bring a blazer, use a collapsible garment bag or a rigid suit carrier. If you pack a jacket in a suitcase, fold it inside-out and place it inside a dry-cleaning bag to prevent deep, heat-set wrinkles.
Adopt a light-colored palette. Stick to light grays, tans, and off-whites. Dark colors absorb direct sunlight, which will raise your body temperature by several degrees while walking between buildings.
Leverage 'internal' layers. Wear a lightweight, breathable undershirt (like bamboo or moisture-wicking tech fabric) under your dress shirt. It creates a barrier that keeps sweat off your outer layer and allows you to strip off the dress shirt if necessary.
