A question for Native Americans, can nonnatives participate in orange shirt day in September?

My life career has recently changed into the field of education/child development, and along with this I am leaning very quickly of all the child remembrance dates related to children and the newest I learned was Orange Shirt Day in September. Honoring in remembering native children who were wrongfully treated by early America. And being in the field of child education and care, I would love to acknowledge it this year now that I'm aware of it.

But I also want to make sure I am not cultural appropriating the wonderful Native couture, and want to ask those whom are Native if it is OK or lack there of, for a nonnative to celebrate by wearing orange on Sept 30th.
