Episode 7

With Joe Lycett hosting, the six remaining home sewers head back in time to the 1980s, attempting to revive the glamorous - and sometimes ridiculous - style of the decade. This is more than a stroll down memory lane, as they tackle the decade's most tailored, fun and over the top garments.

First, judges Patrick Grant and Esme Young challenge the sewers to get down to business with the trickiest pattern so far, a woman's power jacket. Creating the perfect jacket involves grappling with tailoring fabrics and taking on such daunting technical hurdles as lapel construction and inserting shoulder pads, hopefully without getting in a flap. For the transformation challenge, it's party time as the sewers let rip with their imagination, turning high-vis work clothes into party outfits.

In the made-to-measure challenge, the sewers take on their final icon of eighties fashion, the cocktail dress. Working with bold, shiny fabrics, they must create a knee-length-or-above dress that embodies the excess of the 1980s. Who will disco dance their way to garment of the week, and for whom will eighties week signal the end of an era, as they become the seventh sewer to wave goodbye to the Great British Sewing Bee?
