It's Art Week as the remaining sewers tackle three challenges inspired by the world of art. First, Sara reveals they must make a skirt inspired by the modernist movement. The techniques involved include appliqueing abstract shapes and making a sash tied in an enormous, Esme-pleasing bow.In the Transformation Challenge, the sewers are asked to take huge canvases painted by local art students and turn them into dresses making clever use of the sculptural fabric and the painted design. Finally, for the Made to Measure, the sewers take inspiration from the 20th-century surrealist movement, which drew on artists' dreams and subconscious. The sewers dig deep into their own dreams to create fantastical outfits for a mind-bending catwalk.
