Cyrill Gutsch - founder of Parley for the Oceans, an organisation dedicated to throwing a spotlight on the impact of plastic in our environment, and collaborating with a range of designers to reinvent the way in which products are made - talks to Mary about why he believes the new frontier for all areas of design is the creation of new materials.

This week Mary Portas: On Style's fashion correspondent, Miss Jason, is in Cardiff talking to the people he meets about whether the clothes they put on in the morning affect how they feel for the rest of the day.

September is a peak month in the Fashion calendar - it's when designers show their spring and summer collections for the following year. Sarah Mower, Chief Fashion Critic for Vogue.com and the Fashion writer and blogger Susie Lau are among those dedicated to observing and analysing the cavalcade of clothing that takes place in New York, London, Milan, and Paris throughout this equinoctial month. They join Mary to discuss their September highlights and to explain why now Fashion has to enlighten as well as delight.
