An oversized blazer changes the pace of an autumn outfit. It adds a little weight at the shoulder, length through the body and a sense of intention without asking for a formal look.
In Seoul, the blazer often sits over pieces that keep the mood relaxed: a fine knit, a washed tee or a shirt left open at the collar. The contrast is the point—tailoring with clothes that already feel lived in.
Soft Tailoring, Worn Loosely
A good oversized blazer should not look as though it has simply been borrowed. The sleeve needs to fall cleanly, the lapel should hold its line, and the extra room through the body should leave space for a knit or light jacket underneath.
Look closely at the fabric before anything else. Brushed wool, dry flannel and a lightly textured twill each catch autumn light differently. A matte finish keeps the shape calm; a faint grain gives the outfit depth without making it feel busy.
Layers That Still Feel Light
Let the blazer carry the outer line, then keep the rest close to the body. A narrow scarf tucked at the neck, a soft cardigan or a simple jersey layer works well beneath it. Straight denim, tailored shorts with tights or a long skirt keep the proportion grounded. Nothing needs to compete with the jacket.
