Sienna Miller and Oli Green: The Ultimate 'It Couple' Rocking Denim Style

Fashion has always been captivated by stylish couples, from Carolyn Bessette and John F. Kennedy Jr. to Kate Moss and Johnny Depp. There's a certain magic that arises when two people, deeply in love, share a unique sartorial sensibility after all, two heads are often better than one.

It’s no surprise, then, that California-based denim brand Frame has tapped into the cultural appeal of one of Hollywood’s most talked-about couples, Sienna Miller and Oli Green, for its Spring/Summer 2025 campaign. With their 14-year age gap, Miller and Green also represent a May-December romance, making them a perfect fit for the brand's forward-thinking yet timeless image.

Who Is Sienna Miller? 

Sienna Miller’s career trajectory is one that has seen her transition from a model to a successful actress. Born on December 28, 1981, in New York City, Sienna grew up in London and attended the prestigious Lee Strasberg Theatre Institute. She first gained attention in the mid-2000s for her role in Layer Cake and quickly became a household name. Throughout her career, she has worked in both films and television, receiving numerous accolades.

Miller’s personal life has always been under the spotlight, with her relationships, including those with Jude Law and Tom Sturridge, often making headlines. However, it is her most recent relationship with Oli Green that has garnered significant media attention.

The campaign, shot by Frame co-founder and creative director Erik Torstensson (a longtime friend of Miller), captures the couple’s intimate chemistry and nods to iconic 90s denim advertisements, such as the famous “Nothing gets between me and my Calvins.” The styling, effortlessly chic and "model-off-duty," features Miller in a simple white tank top tucked into Frame’s new The Vertical jeans, a classic straight-leg silhouette in rigid denim. Green, meanwhile, rocks the quintessential "Canadian tuxedo"a denim-on-denim look with a relaxed, open-shirt vibe.

Who Is Oli Green? The Man Behind the Public Persona

Oli Green is a British model who has gradually been making a name for himself in the fashion world. Although his career has not reached the same level of fame as his partner’s, he has worked with high-profile brands and been featured in various fashion magazines. Born in the early '90s, Oli's striking good looks and tall stature have made him a standout in the modeling industry.

Green’s personal life, much like Miller’s, has become a subject of interest due to his relationship with the actress. While his career has been on the rise, he is also known for maintaining a relatively low profile when compared to his famous partner. Together, Sienna and Oli make for a stylish and intriguing couple, often seen at high-end events and enjoying private moments together away from the public eye.

Fashion brands have long recognized the power of couples to elevate their campaigns, drawing on both the inherent buzz of their pairing and the feel-good press it generates. French brand The Kooples has practically built its brand identity around this concept, regularly casting real-life couples in its campaigns to evoke a sense of romance in its clothing.

In recent years, celebrity pairings like Kendall Jenner and Bad Bunny for Gucci, Kim Kardashian and Kanye West for Balmain, and Victoria and David Beckham for Emporio Armani have all taken center stage. These couples, whether established or newly paired, reflect the enduring power of love and style in the world of fashion.

Donna Karan was one of the first designers to tap into the influence of celebrity couples, casting Demi Moore and Bruce Willis for one of her early campaigns back in 1996. And for Sienna Miller, this isn’t the first time she’s starred in a campaign with a partner. In 2013, she posed alongside then-boyfriend Tom Sturridge for Burberry’s autumn/winter collection, capturing a playful, romantic vibe in the brand’s iconic trench coats.

How Sienna Miller and Oli Green Met: A Love Story in the Making

Sienna Miller and Oli Green’s relationship began in the midst of Miller’s personal growth and new beginnings. Although the couple initially kept their romance under wraps, they were spotted together in public on several occasions in 2021, sparking rumors of a blossoming relationship. Their chemistry was undeniable, with the two often photographed sharing affectionate moments during outings in London.

According to sources close to the couple, their relationship evolved from a friendship. Miller, who had been through some highly publicized breakups, found solace in Oli Green’s calm and composed demeanor. On the other hand, Green, known for his low-key lifestyle, was drawn to Miller’s vibrant personality and magnetic charm.

While Miller, 43, is a well-established star with a career spanning acting and fashion, Green, 28, is an up-and-coming actor and model. His latest role was as “Russ the checkout guy” in Bridget Jones: Mad About the Boy, and he also portrayed Kate Middleton’s boyfriend, Rupert Finch, in The Crown. Green, whose family has strong ties to both the UK and New York, has also modeled for brands like Burberry, GAP, and Urban Outfitters.

Miller and Green’s romance began in 2021 at a mutual friend's Halloween party. Initially, Miller wasn’t sure about the relationship due to their age difference, but Green eventually persuaded her to give it a chance. The couple welcomed their first child together, a daughter, in December 2023. Miller also has an 11-year-old daughter, Marlowe, with ex-partner Sturridge. Despite the past, the family dynamic is harmonious, with Miller and Green often seen with Marlowe, who even joined them at the Cannes Film Festival last year. Interestingly, Sturridge is now engaged to another fashion icon, Alexa Chung—whom Marlowe has playfully called “way more fashionable,” a remark Miller shared with a smile in her 2023 Vogue interview.

Their Public Appearances: A Fashion-Forward Couple

As a couple, Sienna Miller and Oli Green have frequently graced red carpets and public events. Whether attending high-profile fashion shows, charity events, or casual outings, the two have often been photographed together, showcasing their effortless sense of style.

Their most notable appearance was at the 2022 Met Gala, where they made their public debut as a couple. Dressed in matching high-fashion ensembles, they were the talk of the evening, with fashion critics praising their coordinated looks. Their appearances have not only captivated the media but have also reinforced their status as one of Hollywood’s most stylish couples.

Navigating Fame and Privacy: How They Handle the Spotlight

One of the key aspects of Sienna and Oli’s relationship is their ability to maintain a sense of privacy despite the relentless media attention. Sienna, who has been in the public eye for over two decades, is known for her desire to keep certain aspects of her personal life private. This desire for privacy is something that Oli Green respects, and he has often been seen accompanying Miller to public events without engaging in any overtly public displays of affection.

The couple’s ability to navigate the pressures of fame while keeping their personal moments private has earned them respect from fans and media alike. They are careful about the images they project and are known to balance their professional and personal lives well.
