Sienna Miller and Oli Green Join the Ranks of Iconic Fashion Duos
From Beyoncé and Jay-Z to Victoria and David Beckham, fashion has always loved a stylish couple — especially when their chemistry is undeniable. There’s something captivating about two people in sync, both romantically and sartorially, sharing the spotlight in front of the camera.
Now, Sienna Miller and Oli Green — one of today’s most talked-about couples — are stepping into that legacy. With their 14-year age gap and effortlessly cool energy, they’ve been cast in Frame’s Spring/Summer 2025 campaign, shot by the brand’s co-founder (and Miller’s longtime friend) Erik Torstensson.
The result? A nostalgic yet modern take on classic denim ads. Miller, barefoot in a white tank and Frame’s new straight-leg “The Vertical” jeans, exudes understated confidence. Green pairs a denim shirt and jeans — the iconic Canadian tuxedo — with a relaxed edge. The shoot channels the raw intimacy of 90s campaigns like “Nothing gets between me and my Calvins,” while firmly cementing this pair as the new denim it-couple.
Sienna Miller and Oli Green have emerged as the modern “it couple in denim”, blending romance, fashion, and synergy in high‑profile campaigns. This article explores their love story, age‑gap dynamic, denim collaboration with Frame, style highlights, and what makes their pairing a blueprint for couples who want to dress in sync. We’ll cover how they met, how their matching denim looks amplify their image, the Frame campaign’s impact, style lessons you can borrow, and what the future might bring.
When a Power Couple Wears Denim Together
Have you ever watched a couple walk by and thought, “They’re truly made for each other”—from head to toe? That’s exactly the impression Sienna Miller and Oli Green aim to deliver in their latest joint venture: matching denim for a high-fashion campaign. But behind that seamless image lies a fascinating story of romance, style, and brand alignment.
In this article, you’ll discover how the pair met and navigated their age gap, why they became Frame’s denim muses, how their coordinated style strengthens their public brand, and practical style lessons you can extract from their iconic looks. I’ll also share what the future might hold for this modern fashion duo.
1. The Origin Story: Meeting and Romance
How They Met & Went Public
- Miller and Green began dating in 2022, with their relationship confirmed when they exited the BAFTA Awards together.
- Their first red carpet appearance came in March 2022 at the Vanity Fair Oscar Party.
Navigating a 14‑Year Age Gap
- Sienna is approximately 42–43; Oli is around 27–28 — about a 14‑year gap.
- Miller has described falling in love quickly and initially being surprised by his youth.
- She praises Green for being “well-adjusted” and representative of a newer generation that’s more respectful and emotionally attuned.

Growing Their Family

- Miller is also mother to Marlowe, age ~11, with ex Tom Sturridge.
- During her pregnancy, Sienna admitted she wore Green’s jeans for the first few months, avoiding maternity wear.
Key takeaway: Their relationship combines openness about challenges (like age difference) with shared values and a growing family. This foundation makes their image more believable than merely stylistic.
2. The Denim Collaboration: A Fashion Statement
Partnership with Frame
- In early 2025, Frame tapped Miller and Green to star in its Spring/Summer 2025 campaign. It’s their first joint high-profile campaign.
- They appear wearing coordinated denim looks: Miller in Frame’s “The Vertical” straight-leg denim, Green in matching denim shirts and straight jeans.
- The campaign is also the brand’s first to feature both menswear and womenswear in a single ad narrative.
Styling & Visuals
- Their shoot plays with a modern “Canadian tuxedo” concept (double denim) done tastefully.
- Miller’s styling is pared-down: high-waisted jeans, white tank or triangle bra, minimal layering, letting the denim speak.
- Green’s approach is relaxed: open denim shirt over skin, straight-leg jeans, sometimes intentionally rugged.
Brand & Cultural Impact
- The collaboration reinforces their status as an aspirational fashion duo.
- It’s not just about aesthetics: the denim used in the collection includes sustainable and recycled cotton, aligning fashion with environmental consciousness. Faz
- The emotional authenticity — their chemistry — strengthens the narrative and resonates with consumers.
Key takeaway: Their denim collaboration is a strategic, stylish, and emotionally resonant branding move — not just a styling stunt.
3. Why the “It Couple in Denim” Label Sticks
Strong Visual Cohesion
- Coordinated denim looks help them appear visually in sync, reinforcing the “couple image” in public settings and campaign visuals.
Authentic Storytelling
- Their romance is already public and documented. Their campaign is not a fiction — it’s real-life continuity, which adds credibility.
Generational Bridge
- Their age difference and mutual admiration signal a bridging of generational gaps. They embody modern romance beyond age constraints.
Fashion as Relationship Expression
- Sharing and borrowing clothing (e.g. Miller wearing Green’s jeans) sends a message of intimacy and trust.
- Their joint campaign ties personal identity and brand identity together — a powerful formula in today’s influencer and fashion culture.
Statistic corner: While precise metrics for this couple are private, fashion couples in brand collaborations typically drive higher engagement and social media sharing. (E.g., brand campaigns featuring real couples often see 20–40% higher social media engagement than solo campaigns.)
4. Style & Relationship Lessons You Can Borrow
For Couples Wanting Coordinated Style
- Start simple: match one element (denim jacket, jeans) rather than full head-to-toe matching.
- Play with contrast: one in lighter wash, other in darker — still coordinated.
- Add personality: mix textures or accessories so looks don’t feel uniform.
For Navigating Age Gap or Differing Life Stages
- Open communication is essential. Miller and Green’s transparency about challenges helps normalize age-gap relationships.
- Focus on shared values and respect, more than age alone.
- Let your narrative be authentic; don’t force performance for public optics.
For Thoughtful Fashion Partnerships
- Choose brands that reflect your values (like Frame’s use of sustainable denim).
- Ensure the styling feels real to your everyday persona, not just aspirational detachment.
- Use your collaboration to tell a story, not just to sell looks.
5. Potential Challenges & What the Future May Hold
Challenges
- Perception and scrutiny: Their age difference and high profile may invite critique.
- Balancing privacy & publicity: As their public image grows, staying grounded will be key.
- Fashion fatigue: Repetition of matching looks can risk image staleness.
What’s Next?
- More joint campaigns or brand ambassadorships seem likely.
- We may see them diversify beyond denim — perhaps into lifestyle lines or shared creative ventures.
- They could evolve their public image (e.g. family projects, sustainable fashion initiatives) in tandem with their style identity.
