The In-Betweeners: 15 Great Transitional Coats To Wear Now
Too warm for a winter coat, too wet to go without? These lightweight jackets and trenches are just the thing for navigating autumn’s most unpredictable days.
September weather can be the trickiest of all. When getting dressed in the morning, a forecast warm but wet can throw even the most fashion astute into a panic. Too wet for sandals, too warm for boots, do you risk dodging the showers with just a brolly, or sweat it out in your coat?

FAQs: Transitional Jackets
What is a transitional jacket?
A transitional jacket is a lightweight layer designed for those tricky in-between months when it’s too warm for a proper winter coat but too cool – or wet – to go without. Think trench coats, barn jackets, bombers and lightweight cotton styles.
What jacket should I wear in September?
September calls for something lightweight and breathable that can cope with a change in the weather. A classic trench is hard to beat, while chore jackets, barn jackets and technical bombers are particularly useful for more casual days.
Are trench coats good for autumn?
Yes. The trench coat is arguably the ultimate transitional coat: smart enough for work, easy to throw over almost anything and lightweight enough for milder autumn days. Look for cotton or cotton-blend styles before temperatures really start to drop.
What are the key jacket trends for autumn 2026?
Barn and utility jackets continue to be big news, alongside oversized trenches, high-neck bombers and relaxed chore-style jackets. Khaki, camel and stone are perennial autumn winners, while leopard-print and contrasting collars add a little interest.
What should I look for when buying a transitional coat?
Versatility is key. Choose something roomy enough to accommodate a knit underneath later in the season, but light enough to wear over a T-shirt or shirt now. Water-resistant fabrics are a bonus for navigating autumn showers.
