It's Week 2, and judges Patrick Grant and Esme Young put the 11 remaining sewers through their paces with three challenges themed around activewear.

First, the sewers take on a technical Pattern Challenge, constructing a seven-panel cap. In the Transformation Challenge, they give new life to unwanted cycling gear, turning it into stylish new garments.

Finally, in the Made to Measure, the sewers must create an athleisure outfit – something practical enough for the gym but stylish enough for a coffee shop.

It's week 4, and the 10 remaining sewers celebrate the rich fashion and textile traditions of Korea. Renowned fashion designer Eudon Choi joins as a special guest judge.

In the Pattern Challenge, the sewers take on the jeogori, a historic Korean garment now seen in contemporary womenswear and K-Pop style. In the Transformation Challenge, taekwondo outfits and colourful belts are reimagined into striking new creations.

Finally, in the Made to Measure Challenge, the sewers design evening wear inspired by the cheollik, once worn by military officials and now a symbol of modern Korean fashion.
