Selfridges is having a concept store for an artist, Marc Quinn.
You can find his art works, scarves, jewellery and tattoos (my favourite!) in the concept store on ground floor.

Check other "White Products" in the concept store as well and you may find some great gift ideas for your white Chirstmas. My picks are the total white Dr Martens and the holdall from Nicomede Talavera X Eastpak.
Here is a video of the building process of one of the window from the idea to the final outcome. I am sure you will love it.
