30 Sienna Miller Outfits We Will Never Tire Of

We’ve been hooked on Sienna Miller’s style for some time now. Of course, there was the boho phase of the ’00s, and we all yearned to look good in a low-slung belt and Western boots with the disheveled glamour only Sienna and Kate Moss could really master. But as we’ve grown (and stepped away from questionable accessories), so has Miller’s own aesthetic. We think she could make almost anything look good.

Coined the “Sienna-ssance” by one of our editors, the past few years have catapulted the star’s wardrobe back to the top of our most-wanted lists, thanks to an incredible mix of off-beat red carpet glamour and über-polished weekend wardrobing. 

When it comes to perfecting the art of the smart-casual, ever-elusive notion, Sienna nails it every single time. A little white dress? Paper-bag waist trousers? Summer dresses paired with patent brogues? Red-hot leathers? It seems the actress can pull off anything. So naturally, we’ve set about breaking down the secrets that power her knockout wardrobe. Keep scrolling to see some of Sienna Miller’s very best outfits and the style tricks she swears by.

1. Platforms can look classy.

Style Notes: Fashion might be obsessed with thin-strap sandals this season, but Sienna proves chunky platforms can look just as cool and sexy, especially when paired with a front-split dress and a red lip. 

2. When in doubt, wear a white T-shirt and jeans.

Style Notes: Sienna makes a white T-shirt and jeans look more interesting with a bright red top-handle bag.

Style Notes: Sienna always leans on her red Gucci loafers to pull together a simple ripped-jeans outfit.

4. Dress down your after dark dresses

Slip dresses are still high on the sartorial agenda for party season 2018, though, as Sienna demonstrates, they can look just as sleek worn in daylight hours. Just add a cozy teddy jacket and edgy flats. 

5. Dad sweaters can look cooler than you might think.

Style Notes: The Dad trend that Sienna is into is the chunky cricket sweater, which she paired with a pair of ankle-grazing trousers and black mules.

6. Don't be scared of wearing two prints at once.

Style Notes: Sienna wore three different checks at once, proving that print clashing isn't as scary as you might think. 

7. More can be more.

Style Notes: A sheer dress in clashing prints, big briefs, jewel choker, and bright heels—it shouldn't work, but somehow it does. The key to achieving Sienna's eclectic look is to anchor your outfit with subtle hints of black, as evidenced by her necklace and frock panel. Masterful as ever.  

8. Checked trousers just look just as cool as jeans.

Style Notes: If you're suck in a denim rut, try switching out your jeans for a pair of checked strides. 

9. Sheer dresses can be subtle.

Style Notes: Sienna wore a Sonia Rykiel maxi gown with pleats on the skirt and flared sleeves, proving that a sheer gown can be elegant. 

10. Gold strappy Carrie Bradshaw sandals are very 2018.

Style Notes: At a New York event in June, Sienna wore an orange silky floral midi dress with a pair of gold strappy stilettos. 

11. Use unique accessories to lift any outfit.

Style Notes: As gorgeous as her peach drop-waist dress may be, what really makes Sienna's soirée attire stand out is her excellent choice of accessories. The red half-moon clutch and monochrome Louis Vuitton shoes allow her kooky personality to shine through. 

12. Leopard-print leggings can look chic.

Style Notes: Sienna wore a pair of leopard-print leggings with a faded mustard yellow sweatshirt. She paired the comfy look with a red handbag and a pair of Birkenstock flip-flops. This sounds like a combination that would never work, but somehow Sienna makes it look cool.

13. Pull out all the stops once in a while.

Style Notes: Anything but minimal, Sienna's floor-sweeping dress, tousled to perfection waves, and bright red lip prove that getting properly dressed up is good for the soul. 

14. Basket bags still look super chic.

Style Notes: At a polo event, Sienna wore a white dress with lace sleeves and a Jane Birkin–esque basket bag.

15. Silky slip dresses always look expensive.

Style Notes: This is one of the best looks we’ve seen in some time: an orange silk floor-sweeping slip dress designed by her sister Savannah Miller. Miller paired it with a clashing peach-colored clutch bag and a gold chain necklace.

16. Invest in good denim.

Style Notes: A good pair of jeans can take you anywhere. Case in point? Sienna’s high-rise flares at the Louis Vuitton Paris Fashion Week show.

17. Everyone needs a LWD.

Style Notes: Yes, the LBD is a longtime wardrobe staple, but come the summer months, we’d argue an LWD (little white dress) is just as essential.

18. Bridge the smart-casual gap with wise footwear choices.

Style Notes: Footwear can be tricky when you’re treading the fine line between casual and overly formal. The answer? Brogues every time. Sienna Miller’s Burberry dress at the Wimbledon tennis championships was complemented by studded patent brogues.

19. Never underestimate the power of navy.

Style Notes: When black is too severe, white too whimsical, and red just a tad too loud, navy blue is the holy grail of chic. It always looks polished and is versatile, so the color is the perfect base for letting cool accessories take the lead.

20. Not everything has to be fitted.

Style Notes: When it’s brightening up and you’re ready to ditch the tights (but there’s still a lingering chill in the air), colorful knits and crochet details are the answer, as Sienna Miller in Céline stripes more than proves.

21. Summer is the time to be bold.

Style Notes: If you can’t wear an outrageously colorful frock in the sunshine, when can you? Cue Sienna in bright and bold Dolce & Gabbana.

22. Pick your trends carefully.

Style Notes: Not every trend suits everyone—after all, how boring would that be? Cherry-picking those that’ll flatter you is vital. This season’s high-waisted paper-bag trousers are a perfect choice for Sienna, elongating her legs and accentuating her waist.

23. Dresses are great, but they aren't the only option.

Style Notes: She may be a boho devotee at heart, but even Sienna can’t resist the structural allure of a Céline jumpsuit layered over a little leather.

24. Loafers always look chic.

Style Notes: There’s a reason bombers are in the wardrobe of every street style star and back on the menu for 2018. Slinking around the city is never cooler than when done in a bomber, cozy layers, and Ray-Ban sunglasses.

25. Embrace the mix and match.

Style Notes: In case you haven’t noticed, Sienna isn’t afraid of mixing bold, clashing prints. If you’re wary of going OTT, opt for one busy print paired with a more muted pattern.

26. No matter the decade, accessories are key.

Style Notes: If there’s one thing Sienna Miller knows, it’s the art of accessorizing. Jeans and a parka topped with a beanie sounds—on paper—incredibly low-key. But with the right printed beanie, a well-chosen Mansur Gavriel bucket bag, and tan ankle boots, everything else is elevated.

27. Tailored coats are the perfect partywear finisher.

Style Notes: This military-inspired Burberry coat is the perfect example of how tailored outerwear can add just enough edge to a glitzy party frock.

28. Borrow from the French.

Style Notes: When in doubt, even Sienna looks to French fashion icons for outfit inspiration, like this floral-print jumpsuit from Jeanne Damas’s label, Rouje.

Style Notes: On holiday in St Tropez, Sienna wore the chicest beach outfit we’ve seen in some time. She wore a Dolce & Gabbana leaf-print little cropped top and shorts co-ord set.

30. Pastels always look pretty.
