The ten remaining sewers celebrate clothes from west Africa. Sara Pascoe and judges Patrick Grant and Esme Young are joined by a special guest judge, Nigerian fashion designer Banke Kuku. The Pattern Challenge takes inspiration from a Ghanaian batakari or fugu tunic, which first involves sewing strips of handwoven deboya fabric.In the Transformation Challenge, the sewers focus on Nigeria. They have 90 minutes to turn beautiful hand-dyed adire fabric into stunning dresses by draping the fabric on the stand.Finally, for the Made-to-Measure round, the sewers make boubous, a dramatic and flowing wide-sleeved robe worn by men and women across west Africa. Who will make something to impress all three judges and win Garment of the Week, and who will become the third sewer to leave the competition?
