Lingerie The Great British Sewing Bee : Season 4 Episode 3

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.
