"Project Catwalk" is hosted by a celebrity and judged by a panel with two permanent judges and a third guest judge - typically a fashion designer, fashion model or celebrity from the fashion industry. Ben de Lisi, fashion designer, appears as a mentor for the designers giving his criticism of their garments and offering support. The program takes place in London with designers using a workroom in Istituto Marangoni, shopping for materials at a large fabric store in London's garment district, and living together in a four-storey Georgian townhouse in Central London.
