Sienna Miller's Wimbledon Outfits Throughout The Years, Ranked By Timelessness

The Wimbledon Championships kick off every summer in London, and the event draws not only the world's most elite tennis players, but the who's who across Great Britain, Hollywood, and beyond. Fashionistas also tune in to ooh and ahh at the looks that walk the stadium steps. Actor Sienna Miller was born in New York City but raised in London, and so, of course, she's been a regular at the tournament since the early aughts, around the same time her career took off.

Like her roles, Miller's Wimbledon style has varied throughout the years, but she does tend to lean into the tradition of the affair with some lovely plays on menswear, enduring prints, and classic silhouettes. To that point, Miller has a longstanding relationship with one of the OG American brands, Ralph Lauren; she's reached for the label for many of her Wimbledon appearances. Many of her outfits shy away from trends and fads, but if timelessness is the metric, some looks have been more successful than others.

Sienna Miller attended day 14 of Wimbledon in London in July 2025 wearing a Ralph Lauren ensemble that was boho fun but took some missteps along the way. Between the crocheted bralette top and flowing maxi skirt, Miller's look felt very Y2K-referential — and not in the best way. The strappy stilettos were an odd choice too. 

Had she lost belt and switched the shoes out for cute mules or preppy loafers, maybe this look would've landed higher up. Plus, we're missing the quiet luxurious vibe, which goes hand-in-hand with timelessness. 

Sienna Miller was at day 11 of Wimbledon in London back in July 2015 donning a stark white jumpsuit that was elegantly fuss-free — no knocks there. A gold necklace or a funky bracelet would've helped to elevate the outfit, but Miller looked great, and we especially love the red lip and sideswept updo. But the 'fit doesn't time travel well. 

The square neckline with its geometrical V-cut feels decidedly mid-2010s. If you wore something like this today or tomorrow, eagle-eyed critics would know you pulled it out from the very back of your closet.

Sienna Miller arrived to day 9 of Wimbledon in July 2024 rocking a cute two-piece look featuring a collared crop top and matching mid-length skirt, both dusted in tiny polka dots — a forever print. The choice of color and the clean strappy sandals are timeless details that could work in any era. 

This look would've nabbed a higher spot except it feels like it's trying to be too many things to too many people. A version of this exists in the bestsellers category of every fast-fashion retailer's site, and for that reason it feels more trendy than timeless.

Sienna Miller was hanging out in the Ralph Lauren suite on day 6 of Wimbledon in London in July 2026 draped in a stone-colored three-piece suit that put a funky spin on a classic with baggy slacks. The "in" cut for pants changes, and so silhouettes that sit too far on either end of the spectrum — too baggy or too skinny — can rebut any timelessness arguments. 

Still, some version of this look has been around forever, and we don't think it's going anywhere anytime soon. In fact, Miller made our list of Wimbledon 2026 attendees who crushed menswear-inspired looks.

Sienna Miller showed up to day 7 of Wimbledon in July 2021 donning a navy blue and white striped outfit that would've been at home on any Manhattan socialite summering in the Hamptons. The Ralph Lauren button-down shirt and relaxed trousers felt easy and breezy — and a prime example of quiet luxury. 

If we had to take any timelessness points away, the pajama look did have a moment post-pandemic, but that's one of those vibes that seems to keep coming back around.

If you're after tips for rocking pinstripes outside of the office, look to the outfit Sienna Miller wore to day 7 of Wimbledon in July 2023. The "Burnt" actor chose a Ralph Lauren cornflower blue linen suit — a belted jacked and flare-legged trousers. And her easy blowout was just the right touch. 

Down to the woven bag, the whole look has that dreamy '70s energy, which does take away from its timelessness a bit, but, honestly, has the disco era ever really gone away?

In a rare move, Sienna Miller abandoned her favored separates and instead reached for a delightful little minidress for day 9 of Wimbledon in London in July 2025. Alessandra Rich designed the dress with its puffed sleeves, laced neckline, and charming ruffle details. 

Between the silhouette — which you could find in any decade over the last 100 years — and the delicate floral print that has always been a summertime staple, this 'fit checks all the timelessness boxes. If Miller chose to pull this one out again for Wimbledon 2035, we doubt anyone would bat an eyelash. 

Back in July 2019, Sienna Miller arrived to day 7 of Wimbledon in London wrapped in a Ralph Lauren khaki suit that oozed old-school English sophistication — but not without a couple of flirty, feminine details. 

Miller showcased one of the best unexpected ways to style a blazer by pairing the double-breasted jacket with slacks that were cuffed and tapered at the ankles. She completed the look that could be worn by any age during any time period with knotted summer sandals for a charming, airy touch.

If you're looking for an always-elegant, forever-effortless outfit that has a 99.9% success rate no matter the time period, then follow Sienna Miller's lead and reach for classically-cut blue jeans and a cool white button-down shirt. Miller wore this design to day 11 of Wimbledon in London in July 2016, complete with an earth-toned tote and matching sandals. 

The high-waisted, slack-like cut of the denim only adds to the timeless quality of the whole look. You've got this outfit in your closet, your mother had it in hers, and your daughter just added it to her cart.

In deciding how to rank Sienna Miller's Wimbledon looks by timelessness, we considered how each best held to the tradition associated with the tournament and classic design while still offering stylish elements. We lent favor to outfits that featured ageless silhouettes, that didn't feel too trendy or married to any specific time period, and whose spirit and features we think would stand up against time. Looks that we imagine could be reasonably worn in the future with few (if any) alterations were ranked highest.
