An influencer with many millions of followers on social media decided to post pics wearing a traditional cultural outfit. However, she sparked a considerable backlash for wearing the clothing  — without any pants.

Siew Pui Yi, who has millions of Instagram and Facebook followers, sparked outrage after uploading multiple photos of herself wearing traditional Vietnamese clothing, which is called Ao Dai. The Malaysian model was called out for not wearing the “long-flared” slacks that go with the tunic top.

The model’s thong is plainly visible in photographs taken within the historic Vietnamese town of Hoi An as she releases a paper lantern on the Hoai River, which is a traditional ceremony representing a plea for peace, according to Yahoo News. After the photographs went viral, the Vietnamese community reacted quickly.

According to reports, the photos drew varied reactions, with many Vietnamese netizens calling them “immodest” and “disrespectful” and pleading with the Malaysian influencer to remove them. “Modern sexy is not wrong, but you are wrong to take the Ao Dai, the national dress of Vietnam, I absolutely do not accept it. I think you should delete this photo, Vietnamese people will be very angry because of this,” a Facebook user commented.

“We welcome international friends to come and wear this national costume,” another user wrote, adding that Ao Dai is the traditional costume of the women of Vietnam. “But your style really doesn’t match the national costume. I hope you can take down the post and apologize to us for disrespecting this country’s culture.”
