Eight sewers return to the sewing room to take on delicate lingerie. The three demanding challenges require the sewers to work with the fiddliest of pattern pieces and the most delicate fabric.First, they follow a pattern for a bra which proves testing for even the most dextrous of sewers, requiring precision engineering and some of the smallest pattern pieces ever seen in the sewing room. Next the sewers get their hands on some charity shop silk scarves which they have to transform into a piece of lingerie. Finally the sewers make luxury robes for their male and female models. It is a challenge that requires a delicate touch, an exacting eye for detail and a fastidious feel for fit.
