On Gaga’s pink Valentino Haute Couture gown at the 2018 Venice Film Festival, Amador recalls, “It was the first premiere, so all of the elements — the grandeur of Venice, the thunderstorm, the introduction of Lady Gaga and this campaign — were cinematic.”

Also on this year’s list is stylist Elizabeth Stewart, who appears on one of the issue’s five covers with “Homecoming” star Julia Roberts.

Best known for her work with Roberts, Cate Blanchett, Sandra Bullock, and Gal Gadot, Stewart says that her most popular look with Roberts was the star’s Stella McCartney gown-and-pant combo at the 2019 Golden Globes.

“Julia has a very specific style but is also interested in the world of fashion and trying new things,” says the Santa Monica-based designer. “So, that alchemy translates into looks like the Stella one.”
