To start the series, Mary visits the wealthy town of Ascot. Its High Street is home to Blinkz, a shop that caters for the fuller-figured woman, owned by size 10 gym fanatic Amanda Collins. Mary is shocked to discover that Amanda's attitude to her plus-size customers leaves a lot to be desired. Blinkz is full of dowdy, baggy, unflattering clothes that most people, whatever their size, wouldn't be seen dead in. As a result nothing is selling and the business is in crisis.
