Can non-Palestinians wear Palestinian thobes?

I just think clothing like this is beautiful. I know wearing keffiyehs is fine, even encouraged, but is there anything off-limits? I know some cultures are more closed-off than others.

If I did buy something like this it’d be from a Palestinian owned shop. I’d wear it for special occasions, if I want to feel pretty within my own home, or if I’m attending a pro-Palestinian event.
