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.

Recommended Fabric – 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.


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.
