WATCH: Meteorologist wardrobe-shamed during live weather report

A male anchor's on-air reaction to a female meteorologist's wardrobe choice has sparked a social media firestorm under the hashtag #sweatergate.

LOS ANGELES — According to The Washington Post, KTLA meteorologist Liberté Chan had planned to wear a black-and-white dress for her 8 a.m. weather report Saturday. But there was a problem.

"The pattern ... didn't work on the weather wall (for some reason, it turned semi-transparent), so after my first weather hit at 6 a.m., I changed," Chan wrote Sunday on her blog, Life of Liberté.

That's when she put on her backup outfit – a black beaded dress.

Cue the trolls.

"It looks like she didn't make it home from her cocktail party last night," one viewer wrote.

"No doubt about it: Liberté Chan's New Year's Eve cocktail dress is inappropriate. That would have been true even if it was a 10 p.m. broadcast," another wrote.

Apparently, others followed suit, so in the middle of Chan's weather report, anchor Chris Burrous handed her a long gray cardigan.

"What's going on?" she asked him. "You want me to put this on? Why? 'Cause it's cold?"

"We're getting a lot of emails," he replied.

After Burrous helped her put on the sweater, Chan said, "I look like a librarian now."

Viewers immediately took to Twitter to slam Burrous for the move.

@KTLA FIRE BURROUS IMMEDIATELY.

Chan, however, said it was all in good fun.

"There is no controversy at KTLA," she wrote on her blog. "My bosses did not order me to put on the cardigan, it was a spontaneous moment. I truly love my job, I like my bosses and enjoy working with my coworkers. Since talking to my team, I want our viewers to know it was never our intention to offend anyone. We are friends on and off the air and if you watch our newscast, you know that."
