The actress’s daughter just made her prom moment one for the fashion archives, and the price tag attached has the internet divided.
On April 19, 2026, Nicole Kidman and Keith Urban’s 17-year-old daughter, Sunday Rose Kidman Urban, shared an Instagram photo with the brief caption “prom <3.” The post quickly went viral as netizens marveled at her elegant gown, which is worth more than most people’s monthly salary.
Sunday looked radiant as she posed on an outdoor staircase wearing a vintage, decorated gown from the Oscar de la Renta Spring 2022 line. The strapless dress showcased a silver sequined bodice shaped like strawberry vines, which cascaded down her hips before blooming into a voluminous white tulle skirt.
Fashion enthusiasts might recognize the piece from the luxury resale site Vestiaire Collective, where a version of the gown recently sold for $5,800. This price represents a significant drop from its initial retail value of $12,900.
Still, it was all for a school prom. Yes, really.
Naturally, reactions online were swift and split right down the middle. Some fans were completely swept up in the look, while others called the whole thing excessive.
“Beautiful dress she looks divine,” one admirer wrote on a Facebook post. Another added, “Overpriced but stunning. Isn’t she already a model. May be on loan [sic].”
Plenty of others skipped the compliments entirely. “Way over the top!” said one commenter, while another went further, adding, “Immoral to spend that on a dress!”
A third kept it blunt: “It’s not the red carpet, only a school formal.”
Some comments had nothing to do with the gown. Sunday’s resemblance to her father caught people off guard on Instagram. “She looks like her Dad,” one person noted, and another agreed, “She’s a mini Keith 😍.”
A few kept things in perspective. “She waited a lifetime to have her daughters and she certainly can afford it. I think its absolutely beautiful and elegant for her age [sic]. ❤️,” one supporter wrote. Others stayed terse, adding, “So unnecessary” and“She looks sad.”
The prom post arrived at a meaningful moment for the Kidman-Urban family. Nicole Kidman recently revealed that Sunday will be joining her at the 2026 Met Gala on May 4, making it an official mother-daughter debut on one of fashion’s biggest nights.
“I’m so, so happy, and my daughter Sunday will be coming,” the “Moulin Rouge” actress said on the March 11 episode of the “Las Culturistas” podcast, noting it would be her third time co-chairing the event. She shares Sunday and her younger sister, Faith Margaret Kidman Urban, 15, with Keith.
With a $12,900 prom dress and a Met Gala invitation already on her spring calendar, Sunday Rose is having quite the season.
