Nicole Kidman’s Daughter Wears $12,900 Oscar de la Renta Gown to Prom

Nicole Kidman’s Daughter Sunday Rose Stuns in $12,900 Designer Gown at High School Prom — And the Internet Is Divided
Nicole Kidman and Keith Urban’s eldest daughter just made her prom night one of the most talked-about celebrity moments of the spring — and it had nothing to do with who she went with.
On April 19, 2026, seventeen-year-old Sunday Rose Kidman Urban posted a single photo to Instagram with a caption that couldn’t have been simpler: “prom 🤍.” Within hours, the image had gone viral. The reason was the dress.
A Gown With a Price Tag That Stopped People Mid-Scroll
Sunday arrived at her school prom wearing a vintage Oscar de la Renta gown from the designer’s Spring 2022 collection — a strapless piece featuring a silver sequined bodice decorated with strawberry vine detailing, which flowed into a full, voluminous white tulle skirt. The overall effect was closer to a red carpet entrance than a school gymnasium.
For fashion followers, the gown was immediately recognizable. A version of the dress recently appeared on the luxury resale platform Vestiaire Collective, where it sold for around $5,800 — already a significant sum. At its original retail price, the gown was listed at $12,900.
For a high school prom. That detail alone was enough to ignite a debate that spread well beyond Sunday’s Instagram page.
The Internet Had Thoughts — Plenty of Them
Reaction online split almost immediately into two camps, and neither side was particularly quiet about it.
On one side, admirers were effusive. “Beautiful dress, she looks divine,” one commenter wrote on a widely shared Facebook post. Others noted her natural elegance and pointed out that with a mother who has walked nearly every major red carpet on the planet, Sunday had grown up with fashion in her blood.
On the other side, the criticism was pointed and persistent. “Way over the top,” wrote one commenter. Another went further, calling it “immoral to spend that on a dress.” A third kept it short: “It’s not the red carpet, only a school formal.”
Some took a more measured position. One supporter noted that Nicole had waited a long time to have her daughters, that she could clearly afford the gesture, and that the dress itself was age-appropriate and genuinely beautiful. “I think it’s absolutely beautiful and elegant for her age,” they wrote.
A small number of comments had nothing to do with fashion at all. Sunday’s resemblance to her father caught several followers off guard, with multiple people noting that she looked strikingly like Keith Urban. “She’s a mini Keith,” one Instagram user wrote, and the observation was echoed widely across both platforms.
A Big Week for the Kidman-Urban Family
The prom photo landed at a particularly significant moment for the family. Just weeks earlier, Nicole Kidman had revealed in an appearance on the Las Culturistas podcast on March 11 that Sunday would be joining her at the 2026 Met Gala on May 4 — making it an official mother-daughter debut on one of fashion’s most-watched nights of the year.
“I’m so, so happy, and my daughter Sunday will be coming,” Nicole said during the interview, noting it would be her third time co-chairing the event.
For Sunday, the timing means she is stepping into spring with two of the most photographed occasions a young woman in her world could attend — back to back, within two weeks of each other.
From a Paris Baby to the Runway
For those who have followed the Kidman-Urban family over the years, Sunday’s prom moment represents a striking transformation. She was born in 2008 and spent her early years largely out of the public eye, appearing occasionally in candid street photos alongside her parents in New York and Los Angeles.
In more recent years, however, Sunday has stepped more deliberately into the fashion world. She attended the Balenciaga Couture show in Paris in June 2024 and, just months later, walked the runway for Miu Miu’s Womenswear Spring-Summer 2025 show during Paris Fashion Week in October 2024 — one of the more visible signals that her emergence as a figure in her own right was well underway.
Since then she has appeared alongside her mother at W Magazine’s Best Performances Party in January 2025, attended New York Fashion Week in February 2026, and joined both Nicole and younger sister Faith Margaret at the Chanel Womenswear show in Paris in October 2025.
Why This Moment Landed So Hard
What made Sunday’s prom post resonate so far beyond the usual celebrity-kid content was its simplicity. The caption was three words and a heart. The setting was an outdoor staircase. There was no stylist credit, no brand tag, no obvious attempt to perform. It read like any teenager’s prom photo.
Except the dress cost more than many people’s monthly mortgage payment.
That tension — the completely ordinary milestone of a high school prom colliding with a price tag most people will never spend on a single item of clothing in their lives — is exactly what drove the conversation. It wasn’t manufactured controversy. It was the natural result of a world where celebrity wealth and everyday life occasionally share the same frame, and the gap between them becomes impossible to ignore.
What Comes Next
With the Met Gala just days away as of publication, Sunday Rose Kidman Urban is about to step onto an even larger stage alongside her mother. For a teenager who has already walked a Paris runway and attended couture shows across two continents, the transition from prom to one of fashion’s most closely watched events is, in her world, perhaps not quite the leap it would be for anyone else.
Whether the dress she chooses for the Met will spark its own debate remains to be seen.
If the prom gown is anything to go by, people will certainly be paying attention.
