It's the grand finale of The Great British Sewing Bee as the three finalists compete for the title of Britain's best amateur sewer, making the most glamourous and extravagant of garments.

Patrick Grant and Esme Young kick things off by challenging the sewers to make a Victoriana-style evening dress. These dresses require delicate fabrics to create the glamorous effect, but they are tricky to handle, especially when the pattern demands a fitted bodice, puff sleeves and frilled cuffs.

Next, it's the sewers' final chance to show off their instinct for design in the Transformation Challenge, as they attempt to turn female party wear into a glamorous men's red-carpet outfit, inspired by figures such as Billy Porter, Timothee Chalamet and Harry Styles.

Finally, they fit a Met Gala-worthy 'two-in-one' dress for their models, who this week are a friend or family member. Creating a dress which transforms from one dress into another whilst on the catwalk will take a feat of engineering and leap of imagination.

The past sewers return for a reunion, while the judges will make their decision then crown this year's best amateur sewer.
