Here's a more detailed explanation:
Cultural Sensitivity:
Thai culture values modesty and decorum, and going topless in public is seen as a breach of these norms.
Potential for Trouble:
While there might not be a specific law against it, authorities or locals could react negatively, potentially leading to unwanted attention or even legal issues.
Focus on Beaches and Hotels:
While you might see topless women on some beaches, it's generally frowned upon in other public areas. It's best to stick to private areas like your hotel pool or beach if you wish to go topless.
Consider Driving Laws:
It's also illegal to drive a car in Thailand shirtless.
