Sara Pascoe welcomes the semi-finalists into the sewing room, and with judges Patrick Grant and Esme Young, sets three 1920s-inspired challenges that will test the sewers' creativity and skill.
First, in the Pattern Challenge, the sewers must recreate iconic plus fours, a staple of 1920s outdoor pursuits, combining practicality and style from the era.
Next, for the Transformation Challenge, the sewers take inspiration from tennis legend Rene Lacoste, inventor of the polo shirt, and are given a selection of polos to turn into modern, colour-blocked garments.
Finally, in the Made to Measure, it's time to create an outfit for a 1920s party. From the bold fashion of Weimar Berlin to the lively style of swinging Soho, it's time to embrace the revolutionary fashion of this iconic decade.
With only four sewers remaining, one will miss out on a place in the final.
