Inspired by her own coveted wardrobe, Sienna Miller’s limited-edition capsule collection with Marks and Spencer taps into the seventies with stylish options designed to be worn for seasons to come. The range has proved incredibly popular with shoppers, who have snapped up the pieces in record time. 

Sienna was spotted at the River Cafe in London celebrating interior designer Kelly Hoppen’s birthday and fashion fans instantly recognised her outfit as part of her Marks and Spencer edit. You can copy her outfit for less as it is currently included in the M&S womenswear sale. 

The printed shirt and trousers typically retail for £39.50 each, but you can get the entire set for £64, saving you £15 off the celebrity-approved outfit. 

Whether you choose to wear the printed pieces individually or together as Sienna has done, you’re guaranteed to look chic and elegant while feeling comfortable. More than 100 people have left high praise for the set on the Marks and Spencer website that is stocked in sizes eight to 18. 

One happy fan wrote: “Love the 60’s 70’s vibe, stylish. Beautifully soft material that sits well and flows; can be dressed up or down. I bought both shirt and trousers to co ordinate with other items or together, fab!” 

The set has been hailed for keeping you cool on hot day, with someone sharing: “This fabric is not only a gorgeous design but feels absolutely fabulous next to the skin. It’s so lovely that I decided to buy the matching trousers when I went to collect the shirt. I’m so glad I did. On the hottest of days, wearing the trousers was like a cool summer breeze against my legs. The shirt is versatile and can be worn either with the matching trousers or in a variety of other ways.”

The trousers are avaliable in short, regular or long lengths to cater for all heights – a feature that is proving popular with people who love how they don’t have to get them altered. 

Described as a ‘dream to wear’, another person was pleased they were able to get their hands on them, explaining: “No wonder these Sienna Miller items are selling out they are absolutely gorgeous. Beautiful fabric. True to size.” 

However, the co-ord isn’t to everyone’s taste and someone commented: “Well made, stylish trousers, with careful pattern matching. My only issue is finding something to go with them as the matching shirt was a bit too pyjama-esque.” 

You can shop the entire Sienna Miller x Marks and Spencer range here. If you find Sienna’s co-ord set out of stock, Debenhams have a lovely alternative – the Abstract Leaf Print Co-ord Shirt and Trousers Set is £38. These Printed Cotton Voile Trousers from Karen Millen are very sophisticated and on sale for £28 down from £69.
