The Row and the Reign of Quiet Luxury: 2025 Career Updates

The biggest story of the Olsen twins' adult lives is their pivot to high fashion with the launch of The Row in 2006. The brand is the antithesis of their former celebrity-driven careers, focusing on impeccable tailoring, luxurious fabrics, and a minimalist aesthetic—a style now widely known as "quiet luxury."

Recent Milestones and Design Philosophy

In a rare interview given in late 2024/early 2025, Mary-Kate and Ashley spoke briefly about their work, emphasizing that their intense privacy is not a "strategic choice" for the brand, but simply because "We're just private people."

This commitment to discretion has not hindered the brand’s success; in fact, it has amplified it. The Row has become a critical and commercial darling, consistently releasing highly anticipated collections.

• CFDA Awards Dominance: The brand has won multiple Council of Fashion Designers of America (CFDA) awards, including the prestigious Accessory Designer of the Year in 2019 and again in 2023, showcasing their continuous influence in the luxury market.
• 2025 Collections: The Row continues its relentless schedule, with the unveiling of their Women's Fall 2025 and Winter 2025 collections, alongside their Spring and Summer 2025 lines. This constant output of high-quality, timeless pieces is a testament to their dedication as designers.
• Global Expansion: The brand continues to expand its global footprint, with major showrooms and retail presence in New York, Los Angeles, and a significant focus on the Paris fashion scene.

The Row's success is built on the idea that true luxury is unassuming and slow, not driven by hype. This philosophy perfectly mirrors the twins' own lives, where their work speaks volumes while they remain silent.

39 and Thriving: Mary-Kate and Ashley’s Private Lives in 2025

While the twins have always guarded their personal lives fiercely, the period leading up to and including 2025 has seen some major life changes for both sisters, moving them into new phases of adulthood.

Ashley Olsen: Marriage and Motherhood

Ashley Olsen has embraced a new, quiet chapter of her life. She married her long-time partner, artist Louis Eisner, in a private ceremony in 2022.

The most significant and recent update is that Ashley and Louis Eisner welcomed their first child, a baby boy named Otto, in 2024. This news was kept completely private until after the birth, a true reflection of the Olsen twins’ commitment to keeping their family life sacred. The couple made a rare joint public appearance in September 2025, a testament to their happy, low-key life.

Mary-Kate Olsen: Finalizing a New Chapter

Mary-Kate Olsen’s personal life also saw a major transition. Her high-profile divorce from French banker Olivier Sarkozy was finalized, concluding a complex period that began with an emergency filing in 2020.

With her divorce resolved, Mary-Kate has maintained her focus on The Row and her passion for equestrianism. She, like her sister, lives a life intentionally removed from the Hollywood spotlight, prioritizing her business and privacy in New York City and the Hamptons.

The Enduring Legacy of the Olsen Twins at 39

At 39 years old, Mary-Kate and Ashley Olsen are no longer just the former child stars who played Michelle Tanner. They are two of the most successful and influential businesswomen in the fashion industry. Their ability to take a childhood brand, Dualstar, and parlay it into a billion-dollar luxury empire, The Row, is a case study in successful reinvention.

Their current age represents a maturity that has brought both personal fulfillment—with Ashley's new family and Mary-Kate's finalized independence—and professional mastery, as The Row continues to set the standard for "quiet luxury" globally. The twins have proven that you can be famous from birth and still choose a life of extraordinary privacy and sophisticated success.
