Her remarks came just weeks after Prince Harry and Meghan Markle visited the country. In her address, Tinubu warned that girls in Nigeria may be enticed to "mimic and try to emulate film stars from America."
"We have to salvage our children," she said, per the Daily Mail. "We see the way they dress. We are not having the Met Gala, and everyone, the nakedness is just everywhere and the men are well-clothed."
Tinubu called on Nigerians to "do something," and tell girls, "we don't accept nakedness in our culture. That is not beautiful. It's not beautiful at all."
"They don't know where they come from," she said of the younger generation, suggesting that their heritage was at risk of being forgotten in favour of American fashion and lifestyle choices.
The first lady went on to recall Markle's visit to the country, asking why she had decided to "come here looking for Africa."
"That is something we have to take home with [us]," she said. "We know who we are. Don't lose who you are."
While some took that to be a jab at Markle, who wore numerous sleeveless and backless outfits while traversing the country with her husband, others interpreted it to be her noting that the duchess had lost touch with her Nigerian roots.
As the Mirror reports, Markle recently revealed that she had 43 percent Nigerian ancestry. During her trip to the African nation, the point was brought up numerous times by both her and Harry.
This year's Met Gala featured numerous revealing dresses, one notably from Doja Cat, who appeared on the red carpet wearing what was essentially a wet t-shirt which appeared to expose her breasts.
