Should I wear my suit on the plane?

No. The humidity on the ground will wilt the fabric before your first meeting. Keep it protected in a garment bag until you reach your destination.

How do I deal with sweat marks?

Wear a high-quality, lightweight undershirt. It acts as a barrier and helps regulate your body temperature, which is essential in tropical heat.

Keeping Business Attire Crisp in Tropical Humidity

To stay professional in the tropics, prioritize lightweight natural fabrics like linen blends and high-twist wool, and always pack your suit jacket in a dedicated garment bag rather than folding it. Use a dry-cleaning plastic cover to minimize friction and wrinkling during transit.

Select the right fabrics. Avoid heavy cottons or polyester. Choose 'tropical weight' wool, linen-cotton blends, or technical moisture-wicking fabrics that look like traditional suiting but breathe significantly better.
Use a rolling technique for shirts. To prevent sharp creases in dress shirts, fold them neatly and roll them tightly from the bottom hem to the collar. Place these at the bottom of your suitcase to prevent weight from flattening them.
Protect the blazer. Turn your blazer inside out before placing it in a garment bag. This keeps the outer fabric clean and minimizes the impact of potential snagging or surface friction.
Manage moisture upon arrival. Hang all business clothes in the bathroom while taking a hot shower immediately upon arrival. The steam helps release wrinkles caused by the flight without the need for an iron.
