Absolutely. A denim jacket is one of the most reliable transitional layers you can reach for once the weather cools. It sits comfortably over knits, sweaters, and blouses, giving you just enough warmth for crisp mornings and cooler evenings without the bulk of a heavier coat. A denim jacket is easy to keep in rotation well beyond summer, and its year-round wearability makes it a dependable choice throughout the entire fall season, no matter how the temperatures shift.
