From Merchant & Mills.

Overcoat meets duster. An oversized coat for striding through town and country with purpose. Make either lined or unlined. The September works for a variety of seasons, in oilskin or wool it can be a proper winter coat, or in linen it feels like a casual throw on.

This is a multi-size paper pattern, sizes 6-18, seam allowances included.

M&M suggested fabrics – Dry oilskin, oilskin, mid – heavyweight linens, 7 – 12oz denim, wool corduroy, cotton twills or canvas. A heavier weight cloth will result in a more structured coat. 

Marcy says, this classic style can be interpreted in sturdy or lighter weight fabrics for all seasons: linen, cotton, denim, wool, cashmere, stable knits, lightweight upholstery fabric. Makes a good 'blank canvas' design for arty interpretations!
