Whether for the office or to elevate a casual outfit, a tailored blazer can work in almost any wardrobe. A classic, notched collar, fully lined, one-button jacket will never go out of style. If you’ve never tried tailoring before, the Jasika Blazer from Closet Core (below) is an excellent pattern to start with. The instructions include modernized tailoring techniques with minimal hand sewing and fusible interfacings. Invest time in fitting a muslin test garment, so your blazer becomes a favorite piece you’ll reach for regularly.
