Grainline Studio - Cortland Trench / 0-18


Sizes: US 0 – 18 / UK 4 – 22 / EUR 32 – 50

With its modern swing shape and length that hits mid-hip, the Cortland is an update on the classic trench. Raglan sleeves give you plenty of movement and room for layering while the storm flaps and generous collar keep out inclement weather. The Cortland also features a double-breasted front closure and roomy welt pockets. All seams are bound, which not only gives your coat a professional finish, but also helps it stand up to wear and tear.

Techniques involved include sewing a straight seam, welt pockets, Hong Kong seam finishing, topstitching, sewing a collar & collar stand, inserting buttonholes, and hand sewing.

SEWING LEVEL: Intermediate

SIZING: Includes sizes 0 – 18. Mia is wearing a size 8 and is 5'5" tall. Shop the Cortland in sizes 14-30 here.


Main Fabric: Lightweight coating or medium weight fabrics such as cotton or tencel twill, gabardine, or linen. Make sure your fabric has drape to allow the swing shape of the coat to hang properly. We recommend fabric weights between 5 – 8 oz.

Pocket Lining Fabric: lightweight cotton fabrics such as chambray, lawn, or pocketing.

Fusible Interfacing: woven or tricot interfacing in a similar, or slightly lighter, weight as your main fabric.
