The contestants go global, taking on garments and techniques from around the world. For the pattern challenge they make a French breton top - and judges Patrick Grant and Esme Young will be looking for perfectly matched stripes and a completely flat neck - before they transform sarongs into completely different garments. In the final round, the sewers must come up with an outfit inspired by Mexican artist Frida Kahlo, known as much for her personal style as for her vivid artwork. Presented by Joe Lycett.
