Irish star Ruth Negga says she will be wearing "a very beautiful dress" as she turns on the style and flies the flag for Ireland at tomorrow night's Oscars ceremony.
However, the part-Ethiopian actress (35), who is up for Best Actress for her part in the historical drama Loving, admitted she is feeling the pressure ahead of the event.
She described her debut at the star-studded Academy Awards in Hollywood's Dolby Theatre as a "once in a lifetime opportunity".
"I'm getting very nervous. The great thing about filming is that you don't really think about the nerves but they are starting to land now," she said.
"But most of all, I'm hoping not to fall over - that's the main goal."
Ruth kept tight-lipped about the details of her dress when asked about it at the annual Oscar Wilde Awards party in Santa Monica.
The Love/Hate star looked stunning in an emerald green ensemble as she posed for photos with fellow Irish actress Caitriona Balfe.
"I'm wearing a very beautiful dress. It does take a long time to get ready but that's something I want to enjoy and savour," she said.
"These are once-in-a-lifetime opportunities and I really want to enjoy it."
Nominated for her role as Mildred Loving, whose mixed-race marriage in Virginia ended up in America's Supreme Court in the 1960s, Ruth will be going up against some stiff competition.
She is in the same category as Meryl Streep for Florence Foster Jenkins, Natalie Portman for Jackie, Isabelle Huppert for Elle. Emma Stone, for La La Land, has been hotly tipped to win.
Speaking to RTE, Ruth said she is still pinching herself over the news of her nomination.
"I think I went into a state of shock. I couldn't really process it. I still can't process it even though I know it's on tomorrow night," she said.
"I felt quite emotional, actually. You just think about how people have seen this film and how it has resonated with them.
"That's very moving, because that's the whole point of performing - for people to see things and have it affect them on whatever level it can."
Other Irish Oscar hopes include Consolata Boyle, the Dublin-born costume designer who has been nominated for her work on Florence Foster Jenkins, the comedy drama about the amateur American soprano who was known for her flamboyant costumes and inability to sing.
Although Consolata is often responsible for dressing some of the world's biggest stars, such as Meryl Streep, she said she will not be stressing over her own outfit tomorrow night.
However, she did say she prefers to keep her own outfits simple when it comes to her daily life.
Consolata was previously given the nod for her wardrobe work on the 2007 hit The Queen starring Helen Mirren.
Colin Farrell is also expected to attend the Oscars after his quirky movie The Lobster was nominated in the category of best Original Screenplay.
