The Crown star, 25, added some statement-making accessories to their custom Miu Miu yellow-beige strapless column dress, including dramatic matching fingerless gloves (which gave their claw-like stiletto-shaped nails a full moment) and a headpiece resembling a swim cap that was secured under their chin.
Corrin, (who notes their gender pronouns as she/they in their Instagram bio) is up for outstanding lead actress in a drama series for the Netflix hit, marking their first-ever Emmy nomination. Corrin (who portrayed Princess Diana) is nominated alongside co-stars Olivia Colman, Tobias Menzies, Gillian Anderson, Helena Bonham Carter and Emerald Fennell.
To achieve Corrin's sunset-toned eye look, makeup artist Florrie White swept the BYREDO Colour Stick in Vienna (a golden hue similar to their dress) across the entire lid, then applied the BYREDO Colour Stick in a champagne shimmer called Solar Flare to add depth and reflection.
"For the rose stained cheeks, I mixed BYREDO Lipsticks in Solid Ground & Vieux Rose and they were melted into the apples of the cheeks," White explained. "BYREDO Chromophobia Lip Balm was used to moisten & add glisten to Emma's already rosebud lips."
"They were doing some pickups for season 3 and they had asked me to come to set where they were filming to do a chemistry read with Josh [O'Connor, who played Prince Charles]," Corrin said in the interview.
"I remember we did the scene a couple of times and then Ben [Caron, the director] turned to Suzanne [Mackie, the producer] and was like, 'Can I do it now?' And he sort of got down and was like, 'Will you be Diana?' It felt kind of like a marriage proposal."
Needless to say Corrin said yes.
The 73rd Emmy Awards, hosted by Cedric the Entertainer, are airing live from 8-11 p.m. ET on CBS.
