What clothes and shoes to wear to Sabah, Malaysia in April

Malaysia has a constant temperature all year round, which is divided into rainy season and dry season. The temperature is about 21-28 degrees. You can wear short-sleeved sandals or spare parts for thin coats. You will need them if you go to genting highlands. You can also choose some bright T-shirts or fancy clothes. If you wear shoes, it is more suitable to wear sandals or flip-flops, and bring a pair of running shoes, because some local temples are not allowed to wear sandals or slippers.
