A GUARDIAN 'BEST BOOK TO LOOK FORWARD TO IN 2025'

It's the 1990s: Britpop is dominating the charts, Kate Moss and Naomi Campbell stare out from the cover of every glossy magazine and British fashion is ripe for reinvention. Leading the charge is a twenty-something Mary Portas who has been brought in to revitalise the department store Harvey Nichols, at the time more likely to be associated with dowagers than daring designers.

With department stores dying and an alpha male senior management team to impress, the pressure to make profit and bring in young customers, Mary would need to roll up her sleeves like never before to prove she was the woman for the job. By the millennium, the store would be renowned for its outrageous, headline-grabbing, traffic-stopping window displays; patronage by style icon Lady Di and Bolly-swigging duo Patsy and Edina of the iconic sitcom Ab Fab - no longer fusty old Harvey Nicols but Harvey Nicks, daaarling! I Shop, Therefore I Am is the story of how she did it.

Mary takes us behind the shop window - to the people who kept the show on the road and the early lessons that shaped her career. Told with her trademark wit, grit and candour, readers will see first-hand how, armed only with the blank canvas of a shop window and her own creativity, Mary created a business empire that has stood the test of time.
