No, making unwanted complements on physical appearance is considered harassment. Knowing how to politely comment on someone's appearance is a learnable skill. (granted there's an assumption that certain kinds of comments on physical appearance are presumed unwanted, but I think that's reasonable.)

That's not correct. It is in fact just any comments. It's strange but true. I know because I just finished a D&I training recently.

That could be true in your jurisdiction. In general it isn't.[1]

Let's agree that anyone who is concerned about workplace sexual harassment should do their own research and not rely on an internet forum for legal advice!
