The precocious actress, who died successful August 2022, recalled the cleanable acceptable of the black, red-lined leather overgarment she wore successful the carnival scene. However, the pants—which went connected to animate American Apparel's best-selling Disco Pants and Kim Kardashian's SKIMS Disco Pant line—were an wholly antithetic story.

"I retrieve going into the wardrobe trailer with our costume designer, Albert Wolsky, and trying connected the outfit for the archetypal time," Olivia remembered. "The pants were fantastic too, but due to the fact that they were really from the '50s, the zipper was broken, truthful I had to beryllium stitched into them."

Despite virtually being sewn into the tight-fitting bottoms, Olivia didn't fto it restrict her memorable show of "You're the One That I Want."

After all, the all-black vixen look—which mirrors the T-Birds' uniform—marks a pivotal infinitesimal successful the movie and encapsulates the emancipation of her character. From the blistery fig to the teased-out curls and look-at-me-makeup, this showcases Sandy's metamorphosis into a bully miss gone bad.

"Olivia Newton-John couldn't hold to get into the sexy spandex," the costume designer revealed to Stylist U.K. successful 2012. "She hated the goody-goody look Sandy has to wear. When she came retired successful those choky achromatic spandex pants, the mode she walked, the mode she behaved—it wholly changed."

Olivia echoed akin sentiments successful her 2018 autobiography, Don't Stop Believin', portion discussing the dichotomy of playing 2 Sandys.

"Sandy #2 was deliciously wild," she wrote, "and determination was a large buildup of excitement wrong maine to yet bring her to life."

While the risqué look proves Sandy's willingness to change, there's besides an underlying connection that the times are evolving.

The daring design represents the commencement of a caller manner era, arsenic the rigid benignant of the 1950s dilatory begins to fade. Additionally, that aforesaid thought was happening IRL erstwhile the movie premiered successful 1978, with the bohemian inclination of the '70s going retired of benignant and the 1980s ushering successful a caller question of strong makeup, perm hairstyles and body-hugging fashion. Think: Olivia's 1981 deed opus "Physical" and the skintight euphony video looks.

Of course, Sandy wasn't the lone 1 to power up her signature benignant successful the film. 

Danny besides undergoes a translation astatine the extremity of the philharmonic by swapping out his chill leather overgarment for a crisp achromatic letterman. And arsenic insignificant arsenic this alteration is, it's noticeable capable to his T-Birds crew.

"I can't judge it. Danny Zuko turned jock," Doody (Barry Pearl) says to the ringleader, arsenic Sonny (Michael Tucci) interjects, "What are you doing, deserting us?"

Danny replies, "You guys can't travel a person each your lives. Come on, guys. You cognize you mean a batch to me, it's conscionable that Sandy does, too, and I'm going to bash thing I tin to get her."

The rest, arsenic they say, has go history.

Four decades later, you're inactive apt to spot a mates dressed as Sandy and Danny for Halloween. It's besides been a root of inspiration for countless runway collections, including Moschino, Jean Paul Gaultier, Mugler, Saint Laurent and many others.

But we'd beryllium a fake and a phony if we didn't tell you more, archer you much astir the value of the musical's other memorable manner moments and the concept down them.

When piecing unneurotic the looks for the cast, Albert pulled references from the 1950s greaser subculture that the T-Birds and their miss gang The Pink Ladies are portion of. But helium besides near country for mentation and imagination.

"I started retired trying to beryllium realistic," Albert previously told Stylist U.K. "But the manager wanted much color. I ended up thinking, 'These radical are each meant to beryllium successful precocious schoolhouse and, yet, they are coloring the grey streaks successful their hair. Why the hellhole americium I trying to beryllium realistic? It's ridiculous!' So we conscionable went huffy with it."

Sandy's wardrobe unsocial features a rainbow of pastels. For her first time of schoolhouse astatine Rydell High, Sandy armors herself with a agleam yellowish poodle skirt, matching cardigan and achromatic fastener down. The added item of her floral hairsbreadth accessories is a subtle reminder of her innocence and girliness.

It's a stark opposition to Pink Ladies person Rizzo (Stockard Channing), who rules the archetypal time of schoolhouse successful a achromatic body-hugging formal with popped collars. And it's lone when Rizzo believes she's large that her wardrobe changes from sexy to sweet, arsenic she wears a brushed cashmere sweater successful pastel purple during her fig "There Are Worse Things I Could Do."

And erstwhile it came clip for prom night, the costumes and the characters went unneurotic similar rama lama lama ka dinga da dinga dong.

Sandy dons a achromatic frilly formal for prom, a wholesome, axenic prime compared to Rizzo's plunging reddish polka dot look and the low-cut strapless gown Marty (Dinah Manoff) wore to drawback the oculus of blistery changeable vigor announcer Vince Fontaine (Edd Byrnes).

And past there's Frenchy (Didi Conn), who looks similar a beauteous blonde pineapple with her bleached hairsbreadth and matching getup. Throughout the film, we spot that Frenchy isn't acrophobic to experimentation with her style but still sticks to what's trendy successful 1958.

Overall, the benignant in Grease has stood the trial of clip and we'll proceed to spot it surge successful popularity as the prequel series, Grease: Rise of the Pink Ladies, premieres April 6 connected Paramount+ and explores the root communicative of the miss clique. 

It turns out that Grease is inactive the word.
