Emma Hayes explains why the fit of our clothes matters, particularly for women. Inviting us to join her journey from fitting rooms to advising on the latest innovations in technology, Emma describes the many failures of size to capture a woman's body. And with many more of us now buying clothes online, and unable to find out before buying it whether a garment which appears to be the right size actually fits, the problem is getting worse. The costs, as she explains, can be serious for the individual, for the business, and for the environment.
