The annual Met Gala - which takes place in New York tonight - is often described as "fashion's biggest night out". It is a fundraising event for the Metropolitan Museum of Art that welcomes celebrities from all walks of life and fashion industry paragons alike. It also signifies the opening of the NY Costume Institute's annual fashion exhibition which this year has the title 'Heavenly Bodies: Fashion and the Catholic Imagination'. Religion has had an impact on the way we dress for many centuries. Clothing is mentioned in the Bible and some might argue that Eve's fig leaf was the earliest fashion statement. But the fashion world is not just influenced by the Catholic Church. Muslim fashion - and the popularity of the 'cool hijab' - is very important today as is a growing demand for modest fashion. Joining Professor Robert Beckford to discuss religion and fashion are Professor Reina Lewis from London School of Fashion UAL, the Rev Sally Hitchiner and New York based fashion journalist Michelle Honig who is a modern Orthodox Jew. Robert also talks to Simon Ward - former Chief Operating Officer for the British Fashion Council - about important ethical questions facing the fashion industry at the moment.
