From The Modern Sewer:
This jacket is the ultimate versatile piece which works well all year round. Make it in everything from wools & wax cottons to unlined versions in heavy linens and cottons.
Fit notes: This is a neat fit with full length sleeves and straight body shape. If you're sewing this piece in wool you might consider a size up to allow for bulky winter layering (optional suggestion, please check the sizing chart before cutting).
Construction techniques: Welt pockets, 2-piece sleeve, collar & facing and a full lining.
