Cultural Appropriation vs Cultural Appreciation

NOTE These are thoughts from an unfinished article from years ago. I am tying to empty out my backlog to start afresh.

I hesitated commenting on the native headdress photo shoot of a white media student who does modelling in Japan, where you can rent kimonos and get painted like a geisha.

The question:
How can we do good cultural appreciation vs bad cultural appropriation? Two prerequisites.

1) The community approves of it, ie has the power over their image and is happy to spread their unique culture for profit or goodwill
2) The community is involved in making it, ie not headdresses made in sweatshops for sporting fans or photo shoots

It is disingenuous to say "Who do I ask permission?" Like kimono shops in Kyoto, permission is everywhere. If you are asking this question seriously, then you should not do it.

The Japanese were insensitive to the use of the headdress because they see it just as a neutral cultural marker, like their kimonos. They were a colonial power and are still an economic one, unlike indigenous people in the USA.
