Addison Rae in a mermaid-inspired Thom Browne CFDA outfit — And her Halloween costume

Allen and Rae tried a few different options before pairing the curve-hugging dress with a signature gray Thom Browne corset that gave Rae an hourglass shape and a string of Mikimoto pearls, giving the idea new meaning for the term “office siren.” “I feel perfect,” she said of the look. The dress flared out under Browne’s exquisite tailoring, reflecting the light, making Rae appear to have just emerged from the water like a mermaid making her way to land to spend the night as a human.

To bring the fantasy further into the real world, Rae worked with legendary makeup artists Pat McGrath, who she calls a “visionary” with a “turquoise heart,” to compliment her golden ocean waves. “Every look she creates speaks volumes and she knows exactly how to make a girl feel beautiful,” says Rae. I am so lucky to work with her during these special moments.”

As for accessories, Rae’s seashell “purse” for the evening looked like she picked it up on the beach on the way to an awards show, and while it wasn’t functional, it added to the ethereal aesthetic of the Miss. “Dara’s mind works in mysteriously wonderful ways and she comes in and says, ‘I have a seashell’ and I’m not sure what that means exactly,” she said. Then she took out this conch shell and it was perfect.” Rae, leaning into the whimsy, playfully posed with it like a “clamshell phone” throughout the night.

The scene is full of foul smell Aquamarine, The charming 2006 film about friendship bears the same name as Rae’s song, starring Sara Paxton as a mermaid with her best friends JoJo, And Emma Roberts. “I watched the movie again for probably the thousandth time, about a week before I went to the studio,” she said. While the song doesn’t entirely reflect the film, Addison was inspired by what words and colors could convey about her own journey of self-discovery. “I wanted to find out what aquamarine meant to me,” she said. “It was just a perfect moment to reflect on my change and feel comfortable with change, embracing it and being consistent with yourself, and really following your gut and heart .”
