As Roxane Gay said, 'the world changes faster than we can fathom in ways that are complicated'.
She was talking about feminism. But given the rapid turnover of its most revered design figures, it isn't too much of a stretch to apply the same sentiment to the fashion industry.
In recent times, six of the industry's biggest brands have lost - and gained - creative directors for one reason or another.
Some have been dumped by houses in which they left an indelible mark, others dumped a house themselves, and at least one came upon a mutual agreement with their bosses to leave.
So who are the dearly departed and who are their replacements?
Read on for the ultimate guide, though this is the fourth time we've had to update it...
Having spent 12 years as creative director, Ricardo Tisci revealed earlier this month that he would be parting ways with the historic fashion house. Speculation has been whizzing around as to who is next in line to fill his shoes, with Women's Wear Daily reporting Off-White designer Virgil Abloh as a serious contender. Tisci, meanwhile, is rumoured to be heading to Versace. Stay tuned.
With recent news that Clare Waight Keller has decided not to renew her contract as Chloé's Creative Director, it's only natural that the fashion industry should be awash with rumours about her replacement. Bets are currently placed on Nicolas Ghesquière's second-in-command at Louis Vuitton, Natacha Levi-Ramsay.
When Dior appointed Raf Simons its creative director in 2012, he ushered in a new chapter for the brand in which the flamboyance of the John Galliano years became a distant memory.
As testament to the significance of this occasion, his first show for the house was attended by many of his industry peers: Donatella Versace, Christopher Kane, Alber Elbaz, Marc Jacobs and Ricardo Tisci among others were all in the audience. A series of critically adored collections (and visually arresting sets) followed.
But in 2015 the round of musical chairs resumed and Simons announced he was leaving the house to focus on his own line - and life.
As we now know, his replacement turned out to be Maria Grazia Chiuri.
While she's already demonstrated a distinctly feminist vision for her new employer, we've yet to see what Simons has in store for his: Calvin Klein.
In a move that aimed to unite 'all Calvin Klein brands under one creative vision', both Francisco Costa (women's creative director) and Italo Zucchelli (men's creative director) left their posts at the company. And in a move that sent a jolt of excitement through the American fashion world, the company announced its appointment of Raf Simons as chief creative officer, overseeing all men's and women's apparel under the Calvin Klein umbrella.
His first collection for the brand will debut at New York Fashion Week this February, following the big reveal of a redesigned logo and new bespoke line.
After just six seasons, Alexander Wang departed Balenciaga for reasons still unknown. When Vetements' Demna Gvsalia was announced as his replacement, the fashion industry reached a state of hysteria not seen for years.
As for Alexander Wang?
His AW16 collection (and what followed) reminded us that - generally - things always work out for the best.
Loved by all as a person and as a designer, Alber Elbaz's surprise departure from Lanvin in 2015 was arguably the most heart-breaking.
Commenting on the matter, Elbaz mentioned the fact that 'everybody in fashion these days needs just a little more time'.
While the industry reverberated with a nodding of heads, fingers pointed to the numerous disputes the Israeli designer had with Lanvin's owner in the months leading up to the event.
As the announcement was made in the same week as Raf Simons' departure from Dior, it was widely speculated Dior was Elbaz's next destination only for Maria Grazia Chiuri to take the post instead.
As for Lanvin, Bouchra Jarrar took the reigns debuting her first collection with the house during the spring/summer 17 season.
When Hedi Slimane replaced Stefano Pilati as Yves Saint Laurent's creative director in 2012, he made a lot of changes: the 'Yves' was dropped from the brand's name; logos were altered; design work was done from his studio in Los Angeles rather than in the brand's Parisian headquarters, and a commercially-minded rock and roll aesthetic ruled supreme.
And then in 2016, he left. And Anthony Vaccarello, previously creative director of Versus, arrived — bringing the logo's beloved 'Y' and a sexually charged new vision with him.
From 2007, Emma Hill had been widely credited with transforming Mulberry into a force to be reckoned with through a series of beloved bags created in tribute to the likes of beloved Brit It girls such as Alexa Chung.
Eventually, however, current affairs caught up with the company and it struggled through the credit crisis, a rough patch that ultimately led to Hill's departure in 2013.
After more than a year of rumours (everyone from Simone Rocha to Sophie Hulme was predicted to be a replacement), Johnny Coca was revealed as the man for the job. Two seasons into the gig, he's set a more fashion forward course for the brand, complete with a ss17 show styled by fashion's woman of the moment, Lotta Volkova.
