Joe Lycett hosts as the five remaining sewers tackle challenges inspired by music and the movies, taking on garments and techniques from the silver screen. First, they must follow a pattern like none they've encountered before, as judges Patrick Grant and Esme Young ask them to make a dress inspired by Baby from Dirty Dancing. The techniques involved in creating the iconic dance dress include a tightly fitted bodice and perfect full circle skirt.Next up, it's the Transformation Challenge, and just like Julie Andrews's Maria in The Sound of Music, the sewers are asked to adapt old curtains into play clothes for children.For their final challenge, the Made to Measure, the sewers take on the disco era with an outfit inspired by the movie Dreamgirls. Tasked with creating a dazzling 1970s-influenced dress fit for dancing the night away, they must ensure it skims the model's body using tricky technical fabrics. But only four of these five talented sewers can make it through to the semi-final.
