No one who saw Delia Bourne in the street would imagine she is marketing boss of the UK's leading erotica businesses. She may wear sexy underwear, but on the outside she looks like a prim and proper headmistress in her endless wardrobe of dark suits. Her husband complains that she doesn't even change out of her daywear to go out for dinner. That's why he and her work colleagues have secretly nominated her for the tough style treatment doled out by Susannah Constantine and Trinny Woodall.No woman over the age of 35 should wear a hemline above the knee, says Susannah, as she dispatches most of Delia's suits to the bin. As the new look Delia emerges, so does Delia's confidence and joie de vivre.
