The ‘Iron Man’ star and Goop entrepreneur wore a vintage, floor-length black and white Valentino gown made from tulle and silk.
But as she walked on stage to present the award for outstanding lead actress in a drama series, she seemed unable to move properly, holding up her skirt while taking short, uncomfortable looking steps.
Now her stylist has shed light on what really happened, in an interview with US publication The Hollywood Reporter.
Paltrow’s stylist Elizabeth Saltzman explained she sourced Paltrow’s gown from the Valentino archives.
Asked about the unusual looking walk, Saltzman, who has also dressed the likes of Saoirse Ronan and Una Thurman, explained: “That’s because in 1963 there were no back slits!”
While a stylist will typically ensure their clients’ clothing fits correctly, and make alterations as necessary, Saltzman explained the vintage gown was left as-is in order to honour the “authentic” nature of a retro design.
“In order to keep the dress authentic, I didn’t want to change Mr. Valentino’s design,” she explained.
“It was a fun way to put our nod towards wearing your clothes more than once, to honour a very dear friend, and to look like a billion dollar babe!”
It’s not just her fashion choices that Paltrow receives help with. Earlier this year, Paltrow revealed she has previously hired a “personal book curator”, too.
Back in 2001, the former actress decided to redesign her Los Angeles home and realised that to complete the gram-worthy look, she needed a good five to six hundred books to fill the empty shelves.
The 46-year-old asked longtime friend, Thatcher Wine, a long-time book collector and the founder of Juniper Books, to complete the task.
