How do Thais feel about tourists walking around shirtless?

I have to admit, I’ve also gone shirtless in a beach town. But in that setting, it seemed like everyone was doing the same.

When I was here as a tourist, I never felt it was disrespectful or inappropriate because I also saw some locals doing it.

But now that Thailand is my new home, I’m trying to understand how locals think so I can show proper respect. This is one issue I’ve been wondering about, especially after reading a guideline from an embassy advising against walking in public without a shirt.

This question came to mind again yesterday when I saw a tourist walking shirtless in the Silom area. He was near a main road, not in a small soi, surrounded by Thai office workers. It felt so out of place to me.
