In the rarefied world of legacy families and quiet cool, few names draw as much curiosity as that of Sofia Coppola’s daughters, Romy and Cosima Mars. Born into a dynasty that has defined American cinema and alternative culture for decades, these two teenage girls are beginning to command attention in their own right—not for who their parents are, but for who they’re becoming.
Stylish, clever, and refreshingly offbeat, Romy and Cosima are emerging as Gen Z’s new muses of downtown New York sophistication. But despite their pedigreed background and increasingly watchful public eye, they’ve grown up largely away from the glare of celebrity culture. Their mother, Sofia Coppola, a filmmaker known for her precise aesthetic and hushed mystique, has been intentional about raising them with a sense of normalcy, privacy, and creative freedom.
So who exactly are Romy and Cosima Mars? What are they like, what do they wear, and how do they exist within a world that’s both intensely famous and fiercely protected? Here’s everything you need to know about the young women redefining what it means to grow up Coppola.
A Hollywood Heritage with a Twist
Romy Croquet Mars, born in November 2006, and her younger sister, Cosima Mars, born in 2010, are the daughters of Sofia Coppola and Thomas Mars, the French lead singer of the Grammy-winning band Phoenix. With a mother who won an Oscar for Lost in Translation and a father whose music shaped the indie scene of the 2000s, the girls have been raised in an atmosphere of quiet creativity.
But unlike many children of celebrities, they’ve been largely absent from red carpets and social media feeds. Until recently.
Romy made headlines in 2023 after a short, self-made video on TikTok went viral. In the now-infamous clip—posted without her parents’ knowledge—she humorously shared that she’d been grounded for attempting to charter a helicopter using her parents’ credit card. The TikTok, which was later deleted, showcased Romy’s dry wit, cinematic eye, and keen sense of irony. “My parents don’t let me have public social media,” she quipped in the video, filming from her family’s kitchen while making pasta.
Though intended as a joke, the video caught fire online. Fans of Sofia Coppola immediately noted the tonal similarities to her mother’s films: the languid pacing, understated humor, and dreamy lighting. Suddenly, everyone wanted to know more about the girl behind the viral moment—and about her younger sister, Cosima, who, true to form, remained quietly offscreen.
Romy: The Budding Auteur
Described by friends as artistic, self-aware, and quietly magnetic, Romy is said to be interested in film, fashion, and music. Her brief appearance on TikTok hinted at natural charisma and a sense of irony well beyond her years—unsurprising, considering her lineage.
Sources close to the family have shared that Romy is currently enrolled at an arts-focused high school in New York City, where she studies film and creative writing. Though she’s yet to make any public announcements about future projects, those who’ve seen her student work say she has a sharp eye and an appreciation for aesthetic detail that feels unmistakably Coppola-esque.
She’s also reportedly obsessed with vintage clothing, listens to everything from Édith Piaf to Tyler, The Creator, and has a small but tightly knit group of friends who share her love for analog photography and French cinema.
“Romy is like a mix of Sofia and Thomas,” a family friend told [Magazine Name]. “She has her mother’s calm, thoughtful presence and her father’s sense of rhythm. She’s very independent but also deeply observant. You get the sense she’s always taking mental notes.”
Cosima: The Mystery Muse
While Romy’s moment of unintentional internet fame placed her under a brighter spotlight, Cosima has remained even more elusive. Born in 2010, she is still too young to have a public profile, but those who know the family say she’s just as creative—and possibly even more reserved.
Described as thoughtful, funny, and bookish, Cosima is often seen alongside her sister in New York, sometimes spotted wearing oversized sunglasses and vintage coats that wouldn’t be out of place in a Wes Anderson film. She’s reportedly interested in visual art and design, and like her sister, attends a private school in Manhattan where creativity is encouraged over conformity.
“Cosima is the quieter of the two, but she has this really strong personal style,” says a stylist who’s worked with their mother. “She’s like a little Margot Tenenbaum—but real.”
Style Beyond Their Years
One of the most striking things about the Mars sisters is their style. Effortless yet curated, it reflects their mother’s minimalist glam aesthetic mixed with Gen Z’s love of thrift, irony, and individuality. Think vintage Miu Miu cardigans, oversized button-downs, ballet flats, and pieces that suggest they inherited more than a few treasures from their mom’s iconic wardrobe.
Romy in particular seems to embody a kind of neo-Sofia aesthetic: soft, intellectual, and slightly melancholic, with just the right amount of rebellion. She’s been photographed at indie film screenings in the East Village, at bookstores in SoHo, and at quiet dinners in Brooklyn with friends who seem more interested in zines and Super 8 film than selfies and social climbing.
Even when snapped by paparazzi—something that happens rarely, thanks to her parents’ famously low profile—Romy tends to look unfazed and composed, often dressed in slouchy trousers, crisp white shirts, or simple slip dresses layered with vintage jewelry.
Cosima’s style leans more playful and colorful, though no less thoughtful. She reportedly loves layering, pattern mixing, and French flea market finds. Together, the sisters feel like a blend of new-age bohemia and classic Upper East Side prep—with a Coppola twist.
Growing Up Between Two Worlds
Raised between the quiet glamour of Manhattan and summers in France, the Mars girls have had a privileged but unusually grounded upbringing. Sofia Coppola, fiercely private herself, has been open about her efforts to give her daughters as normal a life as possible.
“I don’t want them to grow up thinking that being in the spotlight is what matters,” she told an interviewer in a rare comment about motherhood. “I want them to be curious, kind, and to have room to find out who they are outside of what their parents do.”
That intention seems to have worked. Friends of the family describe Romy and Cosima as “well-adjusted, funny, and kind,” with a clear sense of identity and values. They’re growing up in a rarefied world—but one that’s been carefully managed to allow room for creativity, imperfection, and genuine connection.
What’s Next for the Mars Sisters?
While it’s too early to say if either Romy or Cosima will follow their parents into the world of film or music, the interest is certainly there. Romy, especially, seems poised to carve out a creative path, perhaps behind the camera, perhaps in front. And with role models like Sofia Coppola, Kirsten Dunst, and Phoenix’s Thomas Mars surrounding them, both girls have no shortage of inspiration.
But for now, they seem content to remain teenagers—going to school, hanging out with friends, raiding their mother’s closet, and capturing their world one Polaroid at a time.
In a world obsessed with instant fame and overexposure, Romy and Cosima Mars represent something else entirely: style that’s earned, not bought; identity that’s shaped slowly, not rushed; and a sense of self that exists beyond the algorithm.
They may be the daughters of a cinematic icon, but they’re writing their own story—quietly, stylishly, and on their own terms.
