Unless you managed to avoid the internet in the last few days, you'll know that Cannes Film Festival is in full swing, providing – as always – many, many photographs of celebrities wearing many, many different outfits. One person serving particularly good looks is Sienna Miller, who is there to promote Horizon: An American Saga, a multi-part film in which she stars alongside Kevin Costner. For various photocalls and red carpet events, Miller's outfits included a glamorous black Givenchy dress, a Schiaparelli look including a bouclé jacket and jeans and a Chloe dress that reiterated her return to boho. The one look you may have missed, however, is possibly the most exciting – not only is it the perfect daily outfit formula, you can also shop it on the high street.
While giving interviews over the weekend, Miller chose a chic striped shirt and balloon leg trousers, essentially showing us all how to achieve the perfect work outfit. Styled by Harry Lambert, the look was a sweet tribute to Miller's sister, Savannah, as it came from Vivere, the label she founded last year.

An upgrade on your existing shirts, you'll find this will work with jeans, smart trousers and even skirts.

There's a matching waistcoat and jacket available if you want a stylish suit, or simply team these trousers with a white tee and sandals for an easy, everyday outfit.
It's not the first time Miller has worn her sister's new brand. For the launch event, she chose a coat which then, unsurprisingly, sold out. Happily, her shirt and trousers are still in stock, providing you with an upgrade on your existing wardrobe staples. Incredibly versatile, you can wear the shirt to add polish to jeans, style the trousers with a vest top and sandals while it's hot or follow Miller's lead and combine to create an easy, chic outfit. It's without fuss which, as Savannah told me earlier this year, is really her goal with every Vivere collection: 'I’m really in the business of trying to make women feel incredible. I just want the clothes you put on – I want you to not have to think about it.'
