Something I wondered in another thread - the content in UK Vogue is made to be reprinted, sometimes appearing in those other editions a month or more after its first appearance.
So this might mean the main editorial content in any Dec or Jan issue of UK Vogue won't contain obvious references to Christmas, in case it needs to be reused after that time has passed. The editorials might just be winter-spring dressing, with any Christmas-related content just being the articles at the front of the magazine.
In short, Christmas might be cancelled, because it's all about recycling. We shall see.
