In the recent launch of EE, Britain’s first 4G mobile network, Nicole Scherzinger arrived wearing a Twitter dress.
The dress was made from 8m of French silk chiffon, with around 500 Swarovski crystals and 2000 LED lights. The lights displayed tweets sent to the Twitter account @EE and the hashtag #tweetthedress. The dress was created by CuteCircuit, a London-based group specializing in wearable technology. CuteCircuit previously outfitted Katy Perry and U2. The dress can be recharged via USB.
