Remember that Singapore is a tropical country, and you will most likely sweat a lot more than at home, unless home is a tropical country too, therefore, taking along plenty of heavy duty deodorant will prove to be very handy, especially if you plan on enjoying long walk-about tours of the city, shopping, dining and sightseeing. Clothing should consist of light cottons, to keep you cool in the heat, while some long sleeves and long pants or skirts will be ideal for sightseeing religious sites and conservative Muslim regions.
