Early Life and Background

Savannah Elizabeth Louise Miller was born on 30 December 1978 in British Hong Kong, making her 46 years old as of 2025. Her background is a fascinating blend of cultures. Her father, Edwin Miller, is an American art dealer and former banker, while her mother, Josephine Miller, is a South African–born British model. Growing up in a household that valued both art and aesthetics, Savannah was exposed to creativity from a young age.

She has several siblings, including her well-known younger sister Sienna Miller, who is three years younger. Savannah also has two half-brothers, Charles and Stephen, from her father’s side. The sisters share a close bond, and their relationship has influenced both their careers, with Savannah and Sienna famously collaborating in the fashion world.

Education and Training

Savannah’s artistic journey led her to Central Saint Martins, one of the most prestigious fashion schools in the world. She graduated in 2004 with a First-Class BA in Fashion and Knitwear. Her time at Central Saint Martins played a crucial role in refining her technical skills and instilling in her a fearless approach to design. Surrounded by creative talent and industry legends, she absorbed influences that would later define her distinctive style.

First Steps in Fashion

Before establishing herself as an independent designer, Savannah gained invaluable experience working with some of fashion’s most iconic names. She trained under Alexander McQueen, whose daring approach to tailoring and theatrical fashion left a lasting impression on her. She also worked with Matthew Williamson, known for his colorful, feminine designs. These early years gave her both confidence and credibility in a fiercely competitive industry.

Twenty8Twelve – A Family Venture

In 2006, Savannah teamed up with her sister Sienna Miller to co-found the fashion label Twenty8Twelve. The brand quickly became a favorite among fashion lovers, blending a mix of contemporary style with a touch of bohemian flair. Savannah served as co-creative director until 2012, playing a vital role in shaping its direction and success. The sisters’ combined star power helped Twenty8Twelve receive international recognition, but for Savannah, the experience also planted the seeds of her desire to pursue her own vision.

Launching Her Own Label

In 2012, Savannah launched her solo label, Savannah, which initially focused on luxe basics before evolving into vintage-inspired, 1970s-infused pieces. Her designs were celebrated for being wearable yet distinctive—focusing on high-quality fabrics and a sense of understated glamour. Unlike trend-chasing fast fashion, Savannah’s label embodied authenticity, something she has always emphasized in her work.

Bridal Fashion Success

Perhaps Savannah’s most defining career move came in 2016, when she launched Savannah Miller Bridal. The line quickly gained attention for its bohemian yet sophisticated gowns, designed with lace, tulle, chiffon, and silk. Rather than creating overly elaborate dresses, Savannah focused on elegant simplicity—gowns that captured romance without excess. Her designs are frequently described as “rural chic” rather than the often-misused label of “boho chic.”

Her bridal collections have been praised by Vogue UK, Luxury London, and numerous fashion insiders. Brides drawn to her work appreciate her eye for detail, her fluid silhouettes, and her philosophy that a wedding gown should reflect individuality rather than trends.

Vivere and Ready-to-Wear

In 2023, Savannah expanded her portfolio with the launch of Vivere, a ready-to-wear brand that represents her love for craftsmanship and versatile fashion. Vivere highlights Savannah’s ability to balance practicality with beauty, a theme that has consistently defined her career. The collection is rooted in everyday elegance—pieces that women can live in, echoing the name “Vivere,” which means “to live” in Italian.

Personal Life and Family

Savannah’s personal life is as rich as her professional journey. In 2005, she married Nick Skinner, a bushcraft teacher. Together, they had three children: Moses, Lyra, and Bali. For a time, the family lived in Panama, where Savannah experienced a slower, nature-connected lifestyle before returning to the English countryside. After over a decade together, Savannah and Nick separated in 2018.

In December 2022, Savannah married James Whewell, heir to the historic Wyresdale Park estate. The couple now split their time between London and Gloucestershire, where Savannah enjoys the balance of urban creativity and rural tranquility.

Lifestyle and Philosophy

Savannah describes her style as “rural chic,” reflecting her love of nature and authenticity. Her daily routine often begins with a dog walk and coffee before diving into design work, fittings, and marketing for her collections. Unlike many in the fashion industry, she emphasizes balance—ensuring her role as a mother remains at the heart of her life.

She has often said that her personal wedding in 2005 sparked her journey into bridal fashion. When paparazzi images of her gown circulated, she realized there was a place in the market for elegant yet relaxed wedding dresses.

Physical Appearance

Savannah Miller embodies understated elegance not only in her designs but also in her personal presentation. She has a naturally bohemian look, often favoring flowing dresses, natural makeup, and simple styling. Her exact height has not been publicly disclosed, though she is often described as having a tall, graceful figure. With blonde hair and delicate features similar to her sister Sienna, she has an effortlessly chic appearance that aligns with her fashion sensibility.

Net Worth and Achievements

When it comes to finances, Savannah Miller’s net worth is not officially disclosed. Some entertainment and celebrity websites attempt estimates, but they remain speculative and not verifiable. What is certain is that Savannah has built a successful career in both the ready-to-wear and bridal fashion industries, with her collections featured in top fashion publications and worn by countless brides worldwide.

Her true wealth lies in her influence on modern bridal fashion. By redefining what a wedding dress can be, she has helped thousands of women feel authentic and beautiful on their wedding day.

Social Media and Public Presence

Unlike many designers and celebrities, Savannah Miller maintains a low-key presence on social media. She does not appear to have an active public Instagram or Twitter profile dedicated to her personal life. Instead, her brands and collections have dedicated platforms where fans can follow her latest designs. This separation between personal and professional life reflects her preference for authenticity and privacy.
