Packing is, without a doubt, one of the most stressful things about travelling. Lucky for you, packing for Koh Samui might actually be easier than you would think. The tropical island weather calls for easy, lightweight clothes, and there's absolutely no need for heavy, layered clothing that takes up space in your backpack. The fact that Koh Samui is pretty easy-going with clothing also adds to your convenience. Bikinis are perfectly fine on both private and public beaches. However, it is important that you cover up from shoulders to knees when visiting temples and other sacred sites and always choose outfits with modesty in mind for such occasions.
