Bob Mackie sometimes wishes he could turn back time.

The costume designer, who first dressed Cher in 1967, has created some of the singer’s most iconic looks over the years. However, there is one outfit that still makes him blush decades later.

The 84-year-old admitted to Page Six that when Cher slipped into her skimpy sheer bodysuit for 1989's "If I Could Turn Back Time," he urged the star, "Please don’t tell anyone I had anything to do with this because I don’t really approve." Mackie stressed it was Cher who wanted to strip down and make a bold statement for the music video.

"This is not family viewing," he told the performer, 78.

Cher shot the video on board USS Missouri in front of cheering sailors. The outlet noted the video, which showed Cher’s tattooed bottom, sparked controversy.

"Playing the bass guitar is her 12-year-old son [Elijah Blue] – there with her whole being out and everything else!" Mackie recalled to the outlet.

Mackie first dressed Cher when she was a guest on "The Carol Burnett Show." At the time, he was immediately charmed by her.

"She was adorable," said Mackie. "She looked like Audrey Hepburn’s younger sister at that point. Her hair in little pigtails, a little yellow sundress."

When he dressed her up, Mackie said he saw potential.

"I thought I could do anything on her — she'll look amazing," he said. "She could be anything she wanted to be."

Still, Mackie said he was not on board with Cher wearing what he called "the seatbelt outfit," which was paired with a leather motorcycle jacket. He noted that Cher wanted to rock the look "badly."

"There were certain pieces that I was talked into doing," Mackie previously told Fox News Digital. "Even now, I’ll go, ‘Oh my God, why did I say OK to that?’ But when it comes to design, it’s all about your client. You try to please them but also try to protect them and enhance their look. 

"The one particular piece we always laugh about is Cher when she was on the big battleship for the song ‘Turn Back Time.’ She’s out with all these sailors in this sheer biker outfit with a big strip up the crotch."

Mackie said the look was "so vulgar" that he did not tell anyone he had anything to do with it.

"I remember shaking my head and going, ‘Oh, no,’" said Mackie. "Cher wanted to wear it, but oh, it was too much! And then she had her 12-year-old son playing bass in the band, which made it even worse than all those sailors around her."

According to Mackie, even Cher got "very cold feet" – at first.

"She actually put on her biker jacket because she felt so naked," he said. "But it became a popular video, to say the least. She has more confidence than anybody, but on that day, she kind of lost it on that one. She wasn’t used to being around that many sailors all screaming and hollering for her."

Mackie felt the leather jacket made the costume look "more vulgar from the waist down."

"It was just sheer with just one little crotch piece in black," he said. "But people are still talking about it, I guess. [And] Cher is completely comfortable in these kinds of outfits. That’s why they work. She doesn’t pose or do any of that. She just wears them like they’re normal clothes, which still makes me laugh."

Mackie told Variety that the costume was sold at auction for $75,000. That did not stop Cher from wanting to rock it once more. For a tour, she went on to rent it for a year.

Lauren Sanchez has sparked backlash on social media after unveiling a racy look at Donald Trump’s inauguration.

The fiancée of Jeff Bezos, the chairman of Amazon, wore a white Alexander McQueen pantsuit featuring a fitted satin-trimmed blazer with a dangerously low-cut V-neck and wide-leg trousers.

She skipped a traditional blouse and instead opted for a risqué white lace bustier. She completed the look with a fuzzy coat for the frosty day. Sanchez also made heads turn with her signature smoky eye, glossy nude lips and a sleek updo.

DONALD TRUMP SWORN IN AS 47TH PRESIDENT OF THE UNITED STATES

According to reports, Sanchez's eye-popping ensemble retails for at least $1,800.

The children’s book author, pilot and former journalist was accompanied by her billionaire beau, who sported a suit with an oxblood-hued tie.

Many quickly took to social media to criticize the 55-year-old’s look.

"Jeff Bezos future wife Lauren Sanchez is incredibly inappropriately dressed for a state occasion," one critic wrote on X. "Someone should have told her that having her white lace bra out on display is not acceptable."

"Good grief, Lauren Sanchez. Put them away for one day," chimed another.

"Really, a bra plainly visible," another user wrote. "Today is NOT a night club event. Show some class & dignity."

When one user insisted that Sanchez "forgot to put a shirt on," another replied, "Maybe she can get one from Amazon same day shipping." Meanwhile, others joked that the mother of three was "dressed by Victoria’s Secret."

"Just when I was luxuriating in the beauty and class of @FLOTUS45, in walks Lauren Sanchez wearing only a bra," one user said, comparing the Emmy winner to Melania Trump.

The first lady, 54, wore a more modest navy Adam Lippes tailored navy silk wool coat to the inauguration. She completed her look with a navy silk wool pencil skirt and an ivory silk crêpe blouse, along with black leather gloves and a statement-making wide-brimmed hat.

Facebook and Meta CEO Mark Zuckerberg, who was seated next to Sanchez, was also called out on social media, but for a different reason. Viewers of the inauguration couldn't help but notice he seemingly snuck a look at her chest. 

"Zuckerberg was out of control ogling Jeff Bezos’ fiancée!" one X user wrote, while another noted, "This is the most normal thing I have ever seen Zuckerberg do." 

"Mark Zuckerberg was caught Fact Checking," another X user commented.

Sanchez appears to have worn the same form-fitting suit at The New York Times DealBook event in December. She took a sultry selfie at the time for her nearly 900,000 followers.

Summer Anne Lee, a presidential fashion historian and professor at the Fashion Institute of Technology (FIT) told Newsweek that Sanchez’s fashion statement on the historic day left her stunned.

"I gasped when I saw it," Lee admitted about the jaw-dropping outfit. "I imagine this revealing lingerie moment has got to be a 'first' in inauguration fashion history, even if she is just an attendee and not a part of the ceremony."

On Monday, Trump was sworn in as the 47th president. The 78-year-old promised a "revolution of common sense" as he sets out to reshape the country’s institutions.

A cadre of billionaires and tech titans — including Bezos, 61, as well as Mark Zuckerberg, Tim Cook and Sundar Pichai — were given prominent positions in the Capitol Rotunda, mingling with Trump’s incoming team before the ceremony began. Also, there was Elon Musk, the world’s richest man.

After five years of dating, Bezos proposed to Sanchez in May 2023. While the couple hasn’t publicly announced any details about their wedding, Sanchez teased on the "Today" show that she was already prepping for the big day.
