Dress appropriately
Malaysia's dress code is among the top Things to Know Before Traveling to Malaysia. It is very casual due to the oppressive heat. Shorts, sandals, flip-flops, and t-shirts are the standard everywhere, yet they are considered impolite while visiting government offices, which require long slacks, closed-toed shoes, and collared shirts. To conform with local religious sensibilities, avoid wearing exposing clothing in Malaysia's many kampung (villages).
When it comes to beach attire, modesty is also crucial. At big hotels, resorts, and tourist islands off the East Coast like Pulau Perhentian and Pualu Redang, bikinis and speedos are acceptable. On any other beach, where the residents swim fully clothed, it's preferable to wear one-piece bathing suits and knee-length swimming trunks.
You can see numerous lovely religious sights as a result of the unique culture. However, keep in mind that religious and cultural sites may have severe dress codes. Depending on the religion, you may be required to cover your knees and shoulders, remove your shoes before entering, and possibly cover your hair with a scarf if you are a woman. So remember to bring some conservative attire and dress appropriately for the occasion.
