6. Summer Suiting
Lightweight chino suits and unstructured sportcoats are the name of the game in the summer heat. Keep things casual with a pair of canvas sneakers like Vans Authentics. Or you can ditch the sportcoat and roll up the sleeves on any nice button down. Make sure the fit is slim, and wear an undershirt to wick away excess moisture. No joke, it actually works. You can't argue with science people!
