Singapore is a tropical country so you need not worry about winter clothing and you will only need to pack lightweight cotton clothes which are good for the summer. While Singapore is a very fashionable country it is also an expensive country when it comes to clothing unless you are willing to shop at open-air markets and bargain shops. The best options for men are cotton t-shirts and skinny with a few types of denim or pants and the ideal clothing for women are summer dresses, jeans, cotton t-shirts, and tops and shorts. If you are someone who gets cold easily pack a hoodie or a cardigan so you are prepared in case you need it – especially if you are doing some exploring at night.
