In the semi-final of The Great British Sewing Bee series 9, four contestants are challenged with making a men’s trench coat, upcycling cleaning products and a made-to-measure boilder suit to fit a model. For episode nine we have put our detective hats on to discover the sewing patterns from independent designers and commercial pattern houses used in Sewing Bee TV show. The patterns below are all matches or inspired by the designs used in the ninth episode of the Great British Sewing bee series 9. If you haven’t already seen our ultimate guide to the Sewing Bee  do take a look.

The theme was ‘utilitarian clothing’ and all four contestants had to make three garments. The challenges included making a men’s trench coat, upcycling cleaning products and a made-to-measure boiler suit to fit a model. Take a look at our sewing pattern suggestions below, we’ve tried to find the exact patterns used but where we haven’t been able to  we have plenty of suggestions so that you can recreate these looks at home for your handmade wardrobe. Kate also talks through her favourite pattern options from the episode on YouTube in our special mid-week sewing bee vlog.

Sewing Bee: Pattern Picks

Pattern Challenge 1: Trench coat

The first challenge of the ninth episode was to make the office staple, a trench coat. This garment originated as part of a military uniform. The trench coat has 32 pieces, double breasted with eight buttons, storm flaps and epaulettes. Here are some patterns you could try at home.


Simplicity Men’t Trench Coat S9389

Sizing: AA (34 – 42) BB (44 – 52). Please check the size chart and finished garment measurements. Available in the shop: Yes, paper pattern.


Named Isla Trench Coat

This timeless trench coat is a wardrobe staple! Isla is a straight-cut, lined coat with plenty of details, such as a belted collar, a cape, welt pockets, a belt, and tabs on the sleeve openings. There is a vent at the back for added comfort. The double-breasted button fastening adds a classic look which is topped off with double top stitching.

Sizing: EU 32 – 56 (approx. UK 4/6 – 28). Please check the size chart and finished garment measurements. Available in the shop: Yes, PDF, PDF + printed copy shop or paper pattern.


Transformation Challenge 2: cleaning products

In the upcycling challenge contestants had to upcycle cleaning products. Specific patterns weren’t used for these tasks as contestants had to create a garment from existing materials in a fixed time so it’s a bit tricky for us to make sewing pattern suggestions based on these design ideas.


Made-To-Measure Challenge 3: boiler suits

In the last challenge of the semi-final, all the contestants had to sew a made-to-measure boiler suit. Once worn to stoke boilers, the boiler suit is now an iconic garment on the catwalk and high street. Here are our pattern picks for the contestants and where sewing patterns have been self drafted or hacked we have suggested an alternative.
