Olivia Newton-John's turn as Sandy - the ultimate girl-next-door who shoulder-robed her cardigans and wore bows in her hair (until she didn't, of course) - provided one of the most enduring film 'looks' of all time. But in real life, the singer-actor's fashion sense was just as memorable as that black leather jacket and those shiny, skin-tight leggings. Grease came out in 1978 - the era of flared trousers, loud prints and Studio 54 - and her wardrobe embraced all of the above, from the cool sheepskin coats to the disco-adjacent blouses that were a world away from Rydell High. We took a walk down memory lane to dig out her best looks from the '70s and '80s, including the outfit that cemented her style icon status.

1 of 11The Sheepskin Coat
Taken sometime in the '70s, Olivia Newton-John's tinted sunglasses, sheepskin coat and mullet hairstyle was lightyears away from straight-laced Sandy.
2 of 11The Grease Premiere
At the premiere of Grease, its stars, Olivia Newton-John and John Travolta, dressed like their on-screen alter egos (spotted pink tulle for her; black leather for him).
3 of 11The Big Collar
Performing in the '70s, Newton-John wore what would turn out to be two of the decade's biggest hits (power collars and high-waisted jeans).
4 of 11The Striped Waistcoat
On anyone else, a ruffled shirt and striped waistcoat would have spelt a style disaster. On Newton-John, it somehow looked like a precursor to Carrie Bradshaw.
5 of 11The Satin Blouse
Photographed in 1971, Newton-John's apple belt buckle was very 'on-brand' for Sandy.
6 of 11The Popped Collar
The same year her most famous film was released - 1978 - Newton-John hit the iconic Studio 54. The popped collar, the satin jacket and the skin-tight trousers were pure Sandy ('Tell me about it, stud,' Sandy).
7 of 11The Matching Dress And Boots
Performing in LA, she dazzled onstage in a matching mini dress and spangled boots in March 1980.
8 of 11The Flared Trousers
Taken sometime in the '70s, Newton-John wore lipstick red flares and black ankle boots to pose by a pond.
9 of 11The Silk Scarf
Newton-John wore a silk neck scarf, buckled ankle boots and a waistcoat-and-flares combo for this photoshoot at her home in Hertfordshire.
10 of 11The Leather Jacket
The movie glow-up to end all movie glow-ups, Sandy's leather jacket and leggings combo was the look that fuelled an entire fancy dress movement.
11 of 11The Studded Sweatshirt
Her Physical era meant plenty of studded sweatshirts and sweatbands styled with knee-high boots.
