A traditional workwear boilersuit with a gentler feminine fit. Thelma is a wardrobe masterpiece, loose enough to fit all shapes and can be interpreted in many different types of cloths, so make it your own.

Thelma will take time to put together, but make it well and wear it absolutely everywhere. Skill level – experienced.

This is a multi-size paper pattern including sizes 6 – 18. All seam allowances are 1.5cm unless stated otherwise and are included in the pattern.

We would suggest using the following fabrics – medium weight wovens such as sanded twill, 5 – 8oz denims, yard dyed linens with some stability, and cotton poplin. If you are an experienced sewer you could try tencel, tencel/linen, corduroy, more floppy linens, prints and checks.

Fabrics in our gallery:

Denim (size 10) – Washed Denim in Dark (these had been washed a lot before photographing)

Navy (size 8) – Now out of stock but the Navy Sanded Twill is the most similar

Purple (size 16) – Indian Ink

Orange (size 10) – Brick Sanded Twill

Pattern Errata -Front leg (4) it says on the pattern piece ‘cut here for right side’ should say ‘left’. However the instructions are correct.

The tack on the under arm sleeve (at the cuff) the sizing is the wrong way round.

You will need: 18 x 14-18mm Buttons (only 16 buttons if you intend of just using one button at the cuff) 2 x Matching thread 70cm Interfacing Fabric Requirements (with or without nap)
