ET caught up with the 27-year-old Swedish star on the Oscars red carpet, where she admitted that the dress even gave herself some major Princess Belle vibes.

"I think if you would've asked 5-year-old Alicia what her biggest dream was, it was probably to be Belle in Beauty and the Beast," she smiled.

And Vikander couldn't be more flattered at all the attention her dress already received on social media.

"Oh really, that was my thought!" she laughed when ET informed her of all the Belle comparisons she's inspired. "That's so funny! That's hilarious."

"I've just had the privilege of getting to wear dresses that are like pieces of art," she added. "I don't know how many hours … like, it's made by hand. It's fun. You get the opportunity to dress up."

ET chatted with the Danish Girl star earlier this month at the Oscar Nominee Luncheon at the Beverly Hilton Hotel, when she revealed how she comes up with her already much-praised awards season style.

"I work with a woman called Victoria, and she's my dear friend and she inspires me a lot, but then when it actually comes down to what I'm wearing, it's my own decision," she said.

Vikander also said that her boyfriend, Michael Fassbender, doesn't have any input in her gorgeous gown choices.

"It's all me," she explained.
