Their first major book, "What Not to Wear", was published in 2002. It gained them a British Book Award in 2003 for The TV & Film Book of the Year. The book outsold popular television chefs Jamie Oliver and Nigella Lawson when sale figures reached a total of 670,000 copies, selling 300,000 copies in just fifteen weeks. It was also selling 45,000 copies a week at one point, and had sold 250,000 copies before the peak book selling season had even begun. "What Not to Wear" made sales worth £8.7 million which led to a £2 million book deal to produce more of their fashion books.
