I think this is an incredibly important point. I know it sounds corny, but I think designers are at their most successful and creative when they are sincere about their work - they are expressing in their own language and creating something they feel passionate about. A designer such as Karl Lagerfeld may be able to design for a million different houses and somehow hide his own voice throughout (there is a reason he has never been able to hold down his own namesake line over the years...he keeps creating façades and new narratives, so his own identity has to a point become lost, constantly about creating something of the moment), but he is few and far between.
Rather than trying to emulate the fashion stylist, I think it's about being a thoughtful designer. Finding what drives you, rather than what you think will drive others, because although many designers find success with the latter, they don't last. You'll burn out eventually, and with the short attention span of consumers today, they'll forget you as soon as they've tweeted/facebooked/tumblrd you. All the "greats" have designed from a place that is very personal and self-reflexive in its approach, whether it be Yohji, McQueen or Yves Saint Laurent (his work shows that being personal doesn't necessarily mean not being allowed to change completely every season, provided the approach and perspective threads it all together...although many of his weaker collections are fascinating in their efforts against what was going on in his life at the time, something I suppose you can find with any designer/artist/writer/etc).
Everything goes in cycles though - we want things faster, we want things slower. We have the expansion of the slow food movement (food sourced locally, chosen carefully, and cooked with care), the slow print movement (magazines released bi-annually and written in greater depth, or even a backlash against some of the faster reddit type threads in favour of forums and platforms where things can be properly discussed), and I think it's only a matter of time before this becomes more apparent in clothing. Of course fashion will remain fashion and move at a blistering speed, but hopefully more people will turn against fast fashion and look for a more meaningful mode of consuming. Not expecting it to be the vast majority of consumers, but you only need 1% to create a group that has a noticeable impact and influence.
Oh and Kiko, definitely looking forward to more photos
