A place in the quarter-final is at stake, and this week host Sara Pascoe takes the sewers on a trip down memory lane to the 1990s.First up, in the Pattern Challenge, the sewers are asked to make the 90s most popular trousers – cargo pants. Loved by hip-hop musicians and British girl bands alike, these trousers involve grappling with unfamiliar bellows pockets and a fly zip.For the Transformation Challenge, the sewers take household textiles and rustle up a 90s celebrity-themed fancy dress outfit.Finally, in the Made-to-Measure Challenge, the sewers take on the legendry supermodel dress. These bodycon and body-skimming dresses summed up the glamour and decadence of the decade. Who will make it into the quarter-final, and who will take a tumble on the catwalk?
