Bridget Jones's Baby costume designer is new Great British Sewing Bee judge

Updated: 

The Great British Sewing Bee will return with host Claudia Winkleman, and the costume designer of Bridget Jones's Baby as a new judge.

The upcoming fourth series welcomes Esme Young, co-founder of fashion label Swanky Modes, who also dressed the stars of Danny Boyle's Trainspotting.

Young will join Savile Row's Patrick Grant in setting the 10 contestants three different sewing challenges per episode over the course of the eight-week run. 

The weekly tasks are designed to test a variety of skills before the best sewer is awarded garment of the week, and the weakest performer has to leave.

As in previous runs of the BBC Two series, the first challenge facing the sewers will include a surprise dressmaking pattern.

The second will ask the participants to call on their artistic bent and radically alter an existing item in just 90 minutes.

The third challenge allows the sewers to showcase their individual style and ability to fit garments to a real model.

Under the watchful gaze of the judges, everything from satin dressing gowns to tailored jackets will be produced in the endeavour to crown Britain's best amateur sewer.

Matt Chapple from Berkshire, who learned to sew in the army, won the third series of The Great British Sewing Bee in 2015.
