This year and last I feel Selfridges's christmas window display are the best in London. Each window is a different fairytale, such as Jack and the Beanstalk, with the beanstalk made out of denim. Each window has typography in neon lightbulbs, with playful messgaes from the fairytales.
The theme follows instore with oversized hanging baubles from the celling, with the same messages enscribed on top. In greens and reds, and sparkly.
