Teacher suffers ‘Janet Jackson wardrobe’ malfunction during class

It really subtracted from the class.

A teacher learned the pitfalls of fast fashion the hard way when she shared a horror story about having a “Janet Jackson moment” wardrobe malfunction during math class.

Shayla, who uses the TikTok handle @shesgorgeous_btw, recounted when she wore a sweater from online retailer Fashion Nova for the first time to school.

Trouble is, it ripped while she was wearing it.

“Do you recall your teacher’s wardrobe malfunctions? I hope not! Yikes,” the caption for the video, which she posted at the end of January, read.

“So I’m having a great day getting scholars ready for the new quarter and everything’s going great, right?” said the educator, wearing the purple sweater in question.

“Wrong… I lift my hand up and this is what happens.”

Shayla then steps back from the camera to reveal the entire side of the sweater had ripped, exposing her bra and stomach.

“Fashion Nova sweater, first time wearing it, completely busts open right in the middle of my math lesson,” laughed the teacher.

The Post reached out to Shayla and Fashion Nova for comment.

Shayla likened the incident to the infamous 2004 Super Bowl halftime performance in which Jackson accidentally flashed the audience when Justin Timberlake ripped off a piece of the “Rhythm Nation” singer’s costume and exposed her right breast.

The scandal — which has since been called “Nipplegate” — has been the subject of a documentary produced by FX, Hulu and the New York Times called “Malfunction: The Dressing Down of Janet Jackson.”

Several family members of Jackson, 56, slammed the “Cry Me a River” singer, claiming that he used the incident to jump-start his career while Jackson was shunned by the entertainment industry.

“Justin’s solo career took off after that, and Janet was blackballed,” one of Jackson’s family members told The Post in 2018.

There are even some conspiracy theories that Jackson and Timberlake, 42, planned the “malfunction,” but Jackson’s family members have since denied those allegations.

At the time of the performance, the Federal Communications Commission received more than 540,000 complaints and CBS was fined $550,000 by the FCC, although the Supreme Court later ruled in 2012 that the fine was invalid and the company didn’t have to pay.
