As I dress in the morning, I deeply appreciate the craftsmanship and design behind these items, as well as the adventures and people they recall. And while I hope I don’t offend anyone, I find the alternative—the idea that I ought to stay in the cultural lane I was born into—outrageous. No matter how much I love cable-knit sweaters and Gruyere cheese, I don’t want to live in a world where the only cultural inspiration I’m entitled to comes from my roots in Ireland, Switzerland, and Eastern Europe.

There are legitimate reasons to step carefully when dressing ourselves with the clothing, arts, artifacts, or ideas of other cultures. But please, let’s banish the idea that appropriating elements from one another’s cultures is in itself problematic.

Such borrowing is how we got treasures such as New York pizza and Japanese denim—not to mention how the West got democratic discourse, mathematics, and the calendar. Yet as wave upon wave of shrill accusations of cultural appropriation make their way through the Internet outrage cycle, the rhetoric ranges from earnest indignation to patronizing disrespect.

And as we watch artists and celebrities being pilloried and called racist, it’s hard not to fear the reach of the cultural-appropriation police, who jealously track who “owns” what and instantly jump on transgressors.

In the 21st century, cultural appropriation—like globalization—isn’t just inevitable; it’s potentially positive. We have to stop guarding cultures and subcultures in efforts to preserve them. It’s naïve, paternalistic, and counterproductive. Plus, it’s just not how culture or creativity work. The exchange of ideas, styles, and traditions is one of the tenets and joys of a modern, multicultural society.

So how do we move past the finger pointing, and co-exist in a way that’s both creatively open and culturally sensitive? In a word, carefully.

1. Blackface Is Never Okay

This is painfully obvious. Don’t dress up as an ethnic stereotype. Someone else’s culture or race—or an offensive idea of it—should never be a costume or the butt of a joke.

You probably don’t need an example, but U.S. fraternity parties are rife with them. Sports teams such as the Washington Redskins, and their fanbases, continue to fight to keep bigoted names and images as mascots—perpetuating negative stereotypes and pouring salt into old wounds. Time to move on.

2. It’s Important to Pay Homage to Artistry and Ideas, and Acknowledge Their Origins

Cultural appropriation was at the heart of this year’s Costume Institute exhibition, “China: Through the Looking Glass,” at New York’s Metropolitan Museum of Art. There was a great deal of hand-wringing in advance of the gala celebrating the exhibit’s opening—a glitzy event for the fashion industry which many expected to be a minefield for accidental racism (and a goldmine for the cultural-appropriation police).

Instead, the red carpet showcased some splendid examples of cultural appropriation done right. Among the evening’s best-dressed was Rihanna, who navigated the theme with aplomb in a fur-trimmed robe by Guo Pei, a Beijing-based Chinese couturier whose work was also part of the Met’s exhibition. Rihanna’s gown was “imperial yellow,” a shade reserved for the emperors of ancient Chinese dynasties, and perfectly appropriate for pop stars in the 21st century. Rihanna could have worn a Western interpretation, like this stunning Yves Saint Laurent dress Tom Ford designed for the label in 2004, but she won the night by rightfully shining the spotlight on a design from China.
