From Merchant & Mills:
Overcoat meets duster. A coat for striding through town and country with purpose. Choose to 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.
Recommended Fabrics: Dry oilskin, oilskin, mid – heavyweight linens, 7-12 oz denim, wool corduroy, cotton twills or canvas. A heavier weight cloth will result in a more structured coat. For the lining, we’d suggest using Barrier Lining if you are using oilskin. You could also use cotton voile, lightweight linen, cotton poplin, hemp/cotton, lightweight wools or a traditional slip lining.
Sizes: UK 20-28 (for sizes 6-18, click here)
