For a place in the final, the sewers follow the pattern for kimono-inspired dress, they mend old denim using Japanese techniques, and they create an outfit using folding and pleating.

The quarter-finalists go back to the 1930s to make women’s sailor trousers. They also turn men’s shirts into 1930s blouses and fit glamorous bias-cut evening gowns.

The six remaining home sewers head back in time to the 1980s, attempting to revive the glamorous – and sometimes ridiculous – style of that decade.
