Somehow, many celebrities and fashion magazines have yet to figure out that when non-Native Americans don a headdress for fun it's insensitive to the culture. Now, we can add singer Pharell to that growing list of offenders. 

Pharell chose to wear a headdress on the cover of the latest issue of Elle UK.

The singer released a statement about the cover apologizing for his decision. "I respect and honor every kind of race. I am genuinely sorry," Pharell said, according to BuzzFeed.

Elle UK has not released an apology.

Perhaps the thought behind the cover was that Pharrell has taken to wearing many different kinds of bizarre hats lately, but a headdress really should not have been his next choice for headwear.

The cover sparked the creation of the hashtag #NotHappy.

One Twitter user said, "I'm #NOThappy about @Pharrell donning a faux headdress. Though I am #happy he owned his actions. Ppl, Native Americans are #notyourcostume."

Another, very different Tweet said, "I'm seriously disappointed in @Pharrell for wearing a war bonnet on the cover of @ELLEmagazine #nothappy"

"Why do people still think it's ok to wear our ceremonial items? #NotHappy with Pharrell," added one more user.

People also took the singer's Facebook page to express their disappointment.

This is hardly the first time that a magazine has done something to offend Native Americans.

Native Americans were also disappointed with British magazine, AnOther.

A little more than a year ago, AnOther featured Michelle Williams made up to look like a Native American. The magazine said that it didn't mean to offend.

"While we recognize the seriousness of this debate, the image in question in no way intends to mimic, trivialize or stereotype any particular ethnic group or culture, as recent reports suggest," AnOther magazine said in a statement to ABC News.

It's not just British publications that are putting together offensive spreads.

In 2010, Interview Magazine had one white model among many non-white models. The black models looked more like accessories than people. Vogue Netherlands also featured a white model in black face in 2013. And Businessweek Magazine used an illustration to blame minorities for the "aggressive and predatory lending practice of the mortgage industry."

Magazines continue to offend, and no one is learning from their mistakes. Do you think an apology is enough?
