Gok introduces the four fashionistas that he'll be facing as they compete to produce the best outfits. Whilst the fashionistas style their outfits with a limitless budget from designer clothes, Gok has to make four competing outfits from high street only clothes with a budget of only £800. The outfits compete in a fashion face-off with audience members deciding which is better- designer or high street? Gok talks to Geri Halliwell about her fashion past and gives his must have buys for the week. Also, Alexa put stiletto heels to the test on the running track, and meets Roberto Cavalli.
