The media mogul shared a video online to honor one of her favorite designers Gianfranco Ferré. 

"I just adored all of his white shirts and probably have 10 or 12 of them and he passed away in 2007," Winfrey said. "I just kept all the white shirts, and this is one of those white shirts that I haven't been able to wear for the past 10 years."

According to Winfrey, she managed to fit into the shirt saying, "This is what good working out will do."

"Every woman needs a great white button-down shirt. It's an effortless essential! Tap the link in our bio for some recommendations that can become a staple in your closet this spring," the post caption closed.

The 'OWN Network' founder, who wore the white tailored shirt in the clip, detailed the challenges of fitting into the shirt because the size of her breasts had increased. The 70-year-old credited her workout routine for her slimmer bodice, which left some fans perplexed.

Followers quickly questioned whether the former talk show host was really exercising, and not using a weight-loss drug, like Ozempic, instead. 

"Semaglutide, sold under the brand names Ozempic, Wegovy and Rybelsus, is a drug used to treat type 2 diabetes and reduce obesity," the Journal of Investigative Medicine wrote. The drug was approved for use in America in 2017 and approved in Europe five years later. Sales of Wegovy increased fivefold in 2023 and Ozempic became the world's biggest-selling diabetes drug as the go-to for Hollywood starlets. People who received the weekly injection reported their weight dropped by 12% on average after 68 weeks, the Manchester Evening News reported.

After hosting a TV special in March about obesity and the growing popularity of weight-loss drugs, Winfrey shared some of the powerful lessons she learned on CNN's "King Charles," hosted by long-time best friend Gayle King and Charles Barkley.

"If you feel like being in a bigger body is great, and you don't want to do anything about that, and you feel fine, that is beautiful. I really admire people who really believe that," she said, according to TODAY. "Whatever works for you. One of the reasons I wanted to do (the special) is (to) let people make their own choices for their health and well-being." 

"Let's stop the shaming and blaming," Winfrey continued. "The one thing I hope people come away with is knowing that it's a disease and it's in the brain."
