The rule of thumb for anything is if it goes well, change is unnecessary. The French womenswear empire that is Céline has been doing more than well, yet parent company LVMH saw the need to shake it up. Creative director Phoebe Philo’s ten-year incumbency that seemed unrivalled came to an end with Hedi Slimane named as her successor. The brand also revealed expansion plans into menswear, couture and fragrance. Yet, with Slimane’s notorious reputation to forgo archival elements and instil a completely new spirit, is this the change a flourishing brand needs to propel itself further? We shall see.

Speaking of change: A decade ago, who would’ve ever thought any member of the Keeping Up with the Kardashians reality show would be deemed fit to front a luxury fashion campaign? Fast forward to 2018 and the whole clan has been chosen to front Calvin Klein’s latest #MyCalvins campaign series — winning the seal of approval of design bigwig Raf Simons, no less.

From the Kardashians and Jenners’ first collective fashion ad to the 24th Screen Actors Guild Awards’ best-dressed, here are the best fashion ’Grams of the week. Scroll down and get in on the latest.
