Few movie makeovers are as instantly recognisable as Olivia Newton-John's dramatic transformation at the end of Grease.
The final scene sees her character Sandy Olsson swap pastel cardigans and poodle skirts for skin-tight black trousers, towering heels and a cigarette as she joins John Travolta's Danny Zuko for the now-iconic performance of 'You're the One That I Want'.

But according to Olivia herself, the unforgettable reveal had exactly the effect filmmakers were hoping for – with Travolta stopping in his tracks the first time he saw her dressed as "Sandy No. 2".
Writing in her 2018 memoir Don't Stop Believin', Olivia explained that she always viewed Sandy as two separate characters.
"The first Sandy came easily to me because most of us have #1 in us," she wrote. "But we also have a bit of Sandy #2. Number two smoked, wore black leather and high heels... Sandy #2 was deliciously wild and there was a great build-up of excitement inside me to finally bring her to life."
Creating the look proved more complicated than audiences ever realised. Costume designer Albert Wolsky sourced a pair of authentic 1950s black sharkskin trousers, but there was one major problem – the vintage zip had broken.

Rather than risk damaging the only pair available, the costume department stitched Olivia into the trousers every morning before filming.
"My first thought," she recalled, "What if I need to pee? What am I going to do?"
The finishing touches included curly hair styled by Arthur Johns, dramatic eyeliner, bold red lipstick and a pair of red peep-toe stilettos from Olivia's own wardrobe.
When Olivia finally stepped out of her trailer in full costume, she immediately noticed the reaction.
"There were gasps, catcalls and a lot of whistling," she wrote, admitting she couldn't help wondering: "What have I been doing wrong all these months? All these years!"
One person who was particularly taken aback was John Travolta.

At the time, he was filming Danny's solo song 'Sandy' when Olivia walked across the set.
"There he was sitting on that swing set and feigning a broken heart, when I slunk past," she remembered.
"I remember he stopped singing, mid-note, as his head jerked up and his eyes popped."
According to Olivia, he then jumped to his feet shouting: "'Tell me more! Tell me more!'" before the pair burst into laughter because it was "exactly the reaction I wanted."
Travolta later admitted his surprise wasn't an act. "I couldn't believe it," he recalled. "It was just so right to see her with that Marilyn Monroe hairdo, holding the cigarette, and in those sky-high heels. It was just too good to believe. It was so perfect."
He added that he instantly realised cinemagoers would feel the same way.
"I knew the audience would have the exact same reaction that I was having – a heart palpitation."

For Olivia, however, the makeover represented something much more personal than an iconic movie moment.
She described stepping into Sandy's alter ego as "empowering", saying it gave her the confidence to embrace a side of herself she had rarely shown before.
"I was more of a hippie-bohemian type when it came to my personal dressing style, and this was va-va-va-boom!" she wrote.

Responding to later criticism that Sandy's transformation sent the wrong message to young women, Olivia insisted it was never about changing for a man.
"It was about choice," she explained. "Wear those pants, or a dress down to the floor. Empowerment comes from calling your own shots and being who you want to be."
She also believed the famous outfit had a lasting impact on her own image, giving her the confidence to release her 1981 album Physical and embrace a bolder public persona in the years that followed.
"That last scene in Grease instantly changed my image," she wrote, before concluding with one final thought about Sandy's unforgettable reinvention: "One thing was clear: Sandra Dee was no more."
