2. Layered Over a Chunky Knit Sweater
This is the most undeniably cozy oversized blazer outfit for fall, and it’s surprisingly easy to pull off. The trick is choosing a thin-to-medium-weight knit that won’t add too much bulk under the blazer. A fine merino or cashmere sweater in a fall color like cream, mustard, burgundy, or forest green works beautifully. The blazer goes on top and stays open so you can actually see the sweater underneath.
Pair this combination with straight trousers, dark jeans, or even a pleated midi skirt. The contrast between the soft sweater and the structured blazer is what makes the outfit interesting. Finish with a pair of leather loafers, Chelsea boots, or chunky boots depending on the weather. A long pendant necklace peeking out from under the sweater adds a nice touch.
If you’re worried about looking bulky, look for a blazer with a slightly longer cut that skims the body rather than stopping at the hip. That extra length creates a long, lean line over the sweater. You can also do a half-tuck with the sweater if it’s longer and tunic-style.
