The programme combines beautiful scenery, archive footage highlighting Twiggy's career, and an insight into the life of a woman who shot to fame at the age of 16 and is still making headlines more than 40 years later.

Twiggy and Alan began their walk in the picture-postcard town of Southwold on the Suffolk coast, near to where Twiggy and her husband Leigh Lawson have a weekend house. It also has a special meaning for Twiggy as a chance encounter in a Southwold pub led to her becoming the face of Marks and Spencer.
