This is a traditional workwear boilersuit with a gentler feminine fit. Thelma is a wardrobe masterpiece, loose enough to fit all shapes. It can be interpreted in many different types of cloths - you’ve got many ways to make it your own.

It will take time to put together, but Thelma promises to be a wardrobe staple to give you years of wear.

Skill level – experienced.

This is a multi-size paper pattern including sizes 6-18 and 20-28. All seam allowances are 1.5cm unless stated otherwise and are included in the pattern.

Merchant & Mills suggests 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.
