It's Week 3, and the theme is design icons. Judges Patrick Grant and Esme Young challenge the sewers to channel fashion's most influential figures across three creative tasks.

First up, in the Pattern Challenge, the sewers put their own spin on the timeless Diane von Furstenberg wrap dress. Then, it's a bold Transformation Challenge as they turn home furnishings into punk-inspired looks, paying tribute to Vivienne Westwood.

Finally, glamour takes over the sewing room in the Made to Measure, where the sewers create luxurious garments inspired by the iconic style of Versace.

This week, it's the fast fashion industry, the second most polluting in the world, with Sara Pascoe leading Reduce, Reuse, Recycle week.

In the Pattern Challenge, the sewers create a zero-waste workwear jacket.

The Transformation Challenge brings a surprise as the sewers enter the sewing room to find two tents. Discarded camping gear is given new life as the sewers transform their tent into a complete outfit.

Finally, in the Made to Measure, inspired by the Make Do and Mend campaign, the sewers raid their wardrobes and those of family and friends to create fresh outfits from garments no longer worn - embracing the essence of sustainability.
