It's interesting to note how a look is inspired, a trend emerges and then trickles down to the masses. All you need are a few early adopters (marketing finally comes in handy) and then the rest is history. Reminds me of the Miranda Priestly quote in the Devil Wears Prada about cerulean blue and how influential those in the fashion industry are, even to those who care little about what they wear. "It's sort of comical how you think that you've made a choice that exempts you from the fashion industry when, in fact, you're wearing the sweater that was selected for you by the people in this room from a pile of stuff. "
But back to the point - I've been noticing a lot of Australian designers referencing this pyjama look in their A/W collections (see Maurie & Eve and Friend of Mine for a more subtle influence with the piping). Not sure how winter it is (Celine featured this style for spring) - the lightweight, loose style silk pieces seem all about summer to me, especially with the bright print against the white. Then again, pyjamas are worn all year round so I suppose you can't tie this look to a season. It's taken a little under two years for the Australian market to be hit by the pyjama look (having designers work seasons in advance means they can't adopt trends straight away). I'll give it mid next year until we start seeing knock offs at Supre.
