Besides the main site, the livestream will also be broadcasted on Facebook, large screens at its Oxford Circus flagship in London, the websites of 200+ media partners and pinned to the top of its Twitter page, but all the extras mentioned above will only be available on The experience has also been optimized for desktop viewing, meaning that mobile viewers may prefer to watch the livestream through Twitter.

Shopping is also part and parcel of the experience: Makeup purchases will arrive within 48 hours in the 100+ markets ships to, while clothes and accessories will ship in six to eight weeks which is well ahead of the official arrival in stores (January 2013).
