The Great British Sewing Bee reaches its dramatic denouement, as the three finalists compete for the title of Britain’s best amateur sewer, taking on a trio of challenges for special occasions.

Judges Patrick Grant and Esme Young start by challenging the sewers to make a little girl’s bridesmaid dress packed with complex elements including puff sleeves, a lined bodice and a bound buttonhole.

Next, it’s the sewers’ final chance to show off their instinct for design in the Transformation Challenge. They attempt to turn homeware items such as cushions, bead curtains and table cloths into dramatic and fun outfits fit to wear at a summer festival.

Lastly, for the most important Made to Measure challenge of the competition, the sewers attempt to construct and fit glamorous off-the-shoulder evening gowns for their models.
