Indigenous, First Nation or Native American powpow clothing is not a Halloween costume.
The clothing or regalia worn during a powpow shouldn’t be misappropriated as a costume that’s worn during Halloween:
Also, don’t dress as a victim or evacuee of a war like World War 2:
It’s very morally disrespectful to dress for your Halloween costume as a child victim or as a child evacuee of the Holocaust that was done during WW2.
The historic clothing can be used for a respectful situation like a theatrical play or movie that is about the children who were killed or who were luckily evacuated during the Holocaust.
Or think of it like this:
Inappropriate situation: Wearing the clothing as a costume for your personal entertainment.
Appropriate situation: Actors & Actresses wearing the historic clothing to tell a story about the war that happened.
