We've had this conversation many times about slebs being the face of a product. They are either slebs or designers who went to art/design school. The designers who are slebs have credible businesses with history, like Kelly Hoppen and Julien McDonald. Ambitious Holden does not, Ruth Langsford does not, Lisa Snowden/Andrea McLean does not. Shoppy is right, Langsford always stumbles as to fabric content or colour. What she is good at is hand movements when describing the product. Personally I think she is looking a bit dated in her tight tops, slim jeans and stiletto heels. A mumsy trying to look trendy.
Helen Berman is a bona fide designer, has been around for many years, and her collections used to be in an upmarket clothes catalogue and in concessional department stores. She has more design experience in her little finger than that other pretender in baggy trousers Victoria Beckham. 12 years ago I bought a fabulous beige suit with gold flecks of hers, to attend a wedding in Zurich. It cost around £180, was beautifully made and I felt a million dollars in it. I also have a matching dress and bolero jacket which I'll never part with. Quality always counts.
