Brands have long used famous faces in adverts to reliably boost the awareness and sales of their products. But what is it about star endorsements that make people stop and pay attention? And how is a desire for authenticity changing the expectations for celebrity partnerships?

Celebrity endorsements are old hat, but digitisation has bred a discerning consumer that demands transparency, leaving these partnerships feeling inauthentic. Instead – as seen in Nike and FKA Twigs’ ‘Do You Believe in More?’ – brands and celebrities are ‘collaborating’.

All over the world, the Parisienne way of life is a classic point of reference, encompassing a rich yet balanced diet, impeccable dress sense and a natural sense of beauty. Why is the French art de vivre still so fashionable? And how are the country’s female entrepreneurs exporting this lifestyle?

As well as featuring fantastical gadgets and dastardly villains, 2017 movie sequel Kingsman: The Golden Circle celebrates secret agent style. And it’s letting fans replicate the spy look with an official capsule collection launched in collaboration with luxury menswear retailer Mr Porter.
