It feels like we’re currently living through a Siennaissance, of sorts. While Sienna Miller has been working consistently over the last few years, she’s currently enjoying a level of attention that feels more like we’re back in the mid-noughties. Of course, the boho revival (spearheaded by Chloe’s new creative director, Chemena Kamali) has a lot to do with it, what with Miller still acting as the world’s leading authority on how to wear a boho blouse/dress/skirt – delete as appropriate. But it may also have a lot to do with last year’s M&S campaign, which saw Miller named as the brand’s ambassador for autumn/winter, modelling the brand’s finest on billboards and in a glossy TV advert that was beamed into households across the UK. For her next move, Miller decided to leverage the high interest in her personal wardrobe, along with her sheer selling power, resulting in a new design collaboration with M&S, which launched in early June.
One of the items which was the fastest to sell out when the collection initially launched was the printed sarong, which Miller said was inspired by a scarf given to her by her father years ago. Available in two iterations of the same pattern, it's most recently been spotted on Cat Deeley, who's been wearing it on her holiday in the South of France. The good news? One of the patterns is back in stock and on sale, so it's now just £20 for you to add some Sienna Miller vibes to your own holiday wardrobe.

The navy version of this sarong is back in stock and now on sale, so you can channel Deeley's chic holiday vibes for yourself.
Indeed, most excitingly for fans of Miller’s mid-noughties outfits is that she used her own clothes as the starting point for this 33-piece collection, resulting in some styles which look exactly like the originals worn by Miller over the years. The timing couldn't be better but is, Miller insists, a happy coincidence: 'This is so personal to me,' she said at an event to celebrate the collection. 'We designed it a year ago, so way before this resurgence of clothes that I like to wear, so it’s worked out really well that it’s now considered trendy…this is what i would have done irrespective of that.'
While recently, we've seen Miller on the red carpet at Cannes wearing Schiaparelli, Givenchy and yet-to-be-released Chloe creations, she insists that it's the high street where she finds most of her clothes these days: 'I wear a lot of high street, because I'm fickle and really impatient - I get bored of things quickly and you can find amazing things. I have an 11-year old so I am always in Urban Outfitters these day. I like to buy expensive knitwear and designer shoes. For work, I get to wear glamorous things but for day-to-day, there’s no point spending a lot of money when you can get something beautifully made.'
Most recently, Miller was spotted wearing one outfit from her collection on repeat. She was first seen arriving at Glastonbury wearing the exceptionally 70s boho Printed Shirt and Printed Wide Leg Trousers, and was photographed wearing the co-ord again at River Cafe with friends this week. The perfect statement co-ord, you can wear it over your bikini, on holiday or - as it was intended - as a funky pyjama set. Unbelievably, the co-ord is still in stock on the M&S website, and in the summer sales. Shop it while you still can.

Ahead of it going on sale, we (Hannah Banks-Walker, head of fashion commerce and Julia Harvey, shopping editor) decided to try the collection, to let you know exactly what to buy. Luckily, many pieces have just been restocked, so you still have a chance to add some Sienna Miller to your wardrobe.
The Ruffle Dress
Julia: 'Despite its ruffles, this dress felt more casual than the slips in the collection. I'd wear this under a denim jacket on days when I want to feel dressed up but not over-the-top. I don't really wear florals, so the ruffles add some detail to a plain fabric.'

Hannah: 'M&S has cited this dress as the hero piece of the collection. It fits true to size and would be a pretty option for summer parties or weddings. I think I'd want to add an oversized blazer just to balance out the ruffles but I like that the lower part of the skirt is semi-sheer.'

The White Denim
Hannah: 'I'm not usually a jeans kind of girl but, I have to say, the fit on this pair is really good. They're pretty true to size, if a tiny bit big, they sit on your waist and have the perfect wideness of leg (i.e not swampy). They're slightly cropped, too, which is great for summer and there's a lace-up detail at the back. The jacket is really lightweight and feels expensive thanks to the broderie detail – it would be perfect for festivals. I liked the blouse, too, although it is pretty sheer, so you will need to think about your underwear situation...'

The Slip Dress
Julia: I love the ease of this dress. It feels glamorous but, thanks to the minimal '90s vibes, the sort of thing you could put on for a hot evening when you're on holiday. At home, I'd wear oversized jackets over the top to dress it down a bit.'
www.marksandspencer.com
Julia: 'I've been tasked with finding a blue bridesmaid dress for my friend's wedding this summer – and as soon as I tried this on, knew it was a strong contender. The colour is really beautiful (the photos don't do this justice) and I love the ombre detail at the bottom. Even better is that this would be a bridesmaid dress I'd really want to wear again.'
www.marksandspencer.com
The Vintage-Inspired Shift Dress
Hannah: 'I remember seeing pictures of Sienna wearing a printed shift, so for any fans it's a thrill that they can now buy a near-identical copy of her vintage style. The length of this dress is great – not too short – and the 3/4 length sleeves feel really chic. It's the perfect piece to wear with flat sandals by day during the summer, then you could easily dress it up with heels for evening.'
www.marksandspencer.com
The Quilted Jacket
Julia: 'I have to say, in this ensemble I really did feel like I was in cosplay as Sienna Miller, given that we've all seen her in various iterations of this exact outfit over the years. The jacket is great – it feels like really great quality and would go with so much in my wardrobe. I've paired it here with the barrel leg jeans, which give a nod to the horseshoe jeans silhouette (a big denim trend for 2024) without being too voluminous. The side seam details gives a flattering fit whilst giving just the right amount of slouch. If you want these to sit high on the waist, size down, or for a more relaxed fit (very Miller) go for your usual size.
'I'm also wearing the black swimsuit from the collection, which is incredibly flattering, and I've added the boho belt and those wear-everywhere sandals.'

The Printed Co-Ord
Hannah: 'This outfit is so comfortable, it feels like you're wearing your favourite PJs. With the metallic sandals, it makes for the perfect travel outfit or a chic two-piece for hot days – I've already seen photographs of Sienna wearing it in Venice. The shirt has a slightly cropped, boxy silhouette, which would also look great with high-waisted denim. The trousers I want to wear every day throughout the summer – they're that good. As for the bag, consider this a fresh update on summer's usual basket styles.'

The Sarong
Julia: 'I know Miller created this sarong based on a style given to her by her dad and, I have to say, I'm glad she did. This is going to be my outfit every day on holiday, whatever my plans (well, within reason). As I've already mentioned, the swimsuit is incredibly flattering (and comfortable) and this sarong is as close to perfect as you'll ever find. I'd even wear this with heels by night.'
www.marksandspencer.com
The Beaded Dress
Hannah: 'If you want to replicate Sienna's Glastonbury vibes at a festival this year, this dress is the easy way to do it (with wellies, of course). Or consider this your low-maintenance party piece – just add your favourite shoes and you're ready to go.'
www.marksandspencer.com
The Cropped Blouse
Julia: 'If you want to update your trusty white shirt, opt for a pattered blouse - smart enough for the office but equally as good dressed down with denim cut offs and flip flops for the beach - this will be one busy blouse this summer.'
www.marksandspencer.com
The Summer Maxi
Hannah: 'Another easy summer dress to make your hot weather outfits better than ever. Brilliantly, the top is detachable so you could even just wear this as a slip. Two dresses in one for less than £70 – that's the genius of M&S.'
www.marksandspencer.com
The Beaded Tank
Julia: 'Behold Sienna Miller's jeans-and-a-nice-top, I'll be wearing this combo with a red lip for evenings out sipping rosé. Brides take note, as this could easily be paired with white trousers or skirts for the ideal hen-do get up.'
www.marksandspencer.com
The Khaki Jacket
Julia: 'Offering two pieces in one, this jacket could easily be worn open over a tank top or buttoned up as a heavyweight shirt, plus the front pockets give a great nod to 2024s summer safari trend.'
www.marksandspencer.com
There’s a printed shift which is a doppelganger for Miller’s own vintage ‘60s dress, which she bought from Ninth Street Vintage in New York about eight years ago. There’s also a take on the peachy Galvan slip dress she’s worn on several occasions, which is unsurprising given her love of slips. Speaking to Vogue, Miller said:’ ‘Slip dresses are great because there’s something nonchalant about them but they’re also sexy.’ The M&S version is available in the same peachy colour, or a glorious blue – both with ombre detail at the bottom and both perfect for summer weddings.
Renowned for her love of denim, Miller has taken her favourite styles in her wardrobe – from the likes of Margaret Howell, Agolde and B Sides – and created the perfect blue jeans with a wide leg fit, as well as a white pair with a lace-up detail at the back. In terms of shoes, those thong sandals she’s worn on repeat since about 2006 feature, as does a pair of black cowboy mules, which Miller has already been spotted wearing.
‘I have always had a genuine love for M&S - it's a brand that is part of the fabric of British life and holds special associations for so many people,’ says Miller. ‘Seeing the reaction to the autumn campaign that I fronted was phenomenal. To collaborate on a womenswear design project made total sense. I can’t wait to see what customers think of the collection.’
Of course, this collab also makes overt references to some of Miller’s most famous boho pieces. The one and only bag in the collection, for example, is a nod to the beaded Chloe Bracelet bag (designed by Phoebe Philo) which she wore with many outfits, perhaps most notably with her Matthew Williamson dress to the 2004 Vanity Fair Oscars party. There’s also an homage to a recent Chloe dress Miller wore on the red carpet at Cannes – a powder blue ruffled dress which is also available in cream. 'I think everyone looks great in boho, Miller says. 'I think people look beautiful in floaty things in the summer so I’m here for it. I just can’t believe it’s considered vintage as that makes me feel old.'
So you see, any Sienna Miller fan is going to be well served by this collection, which also includes cropped printed jackets, pretty blouses, easy co-ords (also spotted on Miller very recently, as she was photographed in Venice) and beaded mini dresses. There’s a multipurpose sarong inspired by a scarf gifted to her by her father many years ago, as well as an ultra-flattering swimsuit that you could just as easily wear as a base layer under jeans and an undone shirt when it’s really hot.
It's available now but you may want to be quick – Sienna Miller’s selling power is not to be underestimated.

Sourced from Ninth Street Vintage in New York, Miller has worn this dress several times in the last few years. In fact, she loves it so much that she's recreated it for her M&S collection.
www.marksandspencer.com
Miller has also worn Galvan's peachy slip dress multiple times, so it's no surprise there's a similar style in her M&S collection. It's also available in blue and is perfect for weddings or as your wear-forever holiday dress.
www.marksandspencer.com
Available in pink or blue stripe, this is the shirt you can throw on with jeans, tuck into high-waisted trousers or wear open over swimwear on the beach. It does it all – and it looks just like this one Miller wore with jeans.
www.marksandspencer.com
Miller loves white denim – and she makes it look so easy. This pair really is very wearable – there's a lot of stretch in them, there's a lace up detail at the back and they have the perfect wide leg fit that's not too oversized.
www.marksandspencer.com
Miller wore this blue ruffle dress recently at the Cannes Film Festival, further cementing her allegiance to new Chloe (designed by Chemena Kamali) and its return to boho. She was clearly inspired for her own collection, creating this powder blue style which will be ideal for summer events. It's also available in cream.
www.marksandspencer.com
We've seen Miller in an iteration of the classic khaki jacket thousands of times, so it's not entirely surprising that she included one in this collection. The perfect jacket for warmer months, you could make like Sienna and wear yours with denim shorts and thong sandals, which are helpfully also on offer in this collab.
www.marksandspencer.com
It looks like Miller took inspiration from a Ralph Lauren dress she wore in 2011, the top of which looks exactly like this pretty blouse in the M&S collection. Pair with jeans and ballet pumps for an easy outfit that nods to the boho trend without feeling too 2006.
www.marksandspencer.com
It's not an exact match, but the one and only bag in this M&S collection certainly looks like it owes its existence to the Chloe Bracelet bag which Miller wore a lot in the mid-noughties. With its embellished net overlay, it's a fresh alternative to the basket bag this summer.
www.marksandspencer.com
As a collector of denim, Miller clearly knows what makes a pair of jeans truly great. So, you won't be shocked to hear that this barrel leg pair features a contrast side panel and cut-out hem detail giving them the perfect vintage vibes. They look a lot like styles the actor has worn many times – while she's not wearing the exact M&S jeans here, she is wearing the Western mules, which are £65.
www.marksandspencer.com
As the woman who made coin belts a thing, we would have been disappointed had Miller not included one in her M&S collection. Luckily, this is more wearable (and much less naff) than 2005's coin styles, and can be worn with everything from jeans and jackets to summer dresses (à la Miller at Wimbledon in 2022).
When did Sienna Miller x M&S launch?
The collection is available now, online and in 30 stores across the country. Some styles have sold out online, although M&S has just restocked most of the pieces. It's also worth checking out your local store, as stock is still good in many locations.
How much does Sienna Miller x M&S cost?
The collection costs the same as M&S’s usual collections, with the long ruffled dresses among the most expensive items at £89, while the slip dresses are £65. Tops start at £35, while jackets are £55-£65. The sandals are £49.50, the belts £29.50 (sold out online) and the swimsuit is £35 (nearly sold out online).
