Consider Phuket's warm climate when choosing your clothes. You need clothes made of lighter materials like linen. Shorts, t-shirts, and summer dresses are ideal for your time in Phuket. Invest in a pair of good hiking shoes; they will add comfort to your outdoor excursions. You will also need flip-flops, but you can buy them at Phuket markets. The island isn't exactly an upscale destination, but if you are planning to go to fancy bars and restaurants, pack some suitable clothes. This is a coastal destination, which means that you cannot get through your holiday without a swimsuit, so bring a couple of swimsuits. Sunglasses and hats are essential items for your trip as well.
