There is a particular kind of British weather that makes getting dressed feel like a daily negotiation.
The morning starts with a distinctly autumnal chill. By lunchtime, the sun is out and you are wondering why you put on a jumper. Then, naturally, it rains just as you leave the office.
Welcome to transitional dressing.
That awkward but rather brilliant stretch between summer and autumn is less about packing away your entire summer wardrobe and reaching straight for the heaviest coat you own. It is about making small changes. A long sleeve here, a lightweight jacket there, a pair of boots when the moment feels right. The trick is to dress for the temperature you actually have, rather than the season the calendar says you should be in.
And, frankly, that is where autumn dressing gets interesting.
Don't put your summer wardrobe away just yet
The first rule of dressing for early autumn? Don't rush it.
There are still plenty of warm days ahead, so there is no need to abandon dresses, skirts, T-shirts or lighter fabrics just because September has arrived. Instead, start giving your favourite summer pieces a second life.
A cotton dress that felt perfectly summery with sandals can look completely different with a lightweight cardigan, ankle boots and a trench coat thrown over the top. A favourite skirt can stay in rotation with a fine knit. Even shorts can work for longer when paired with a jumper and loafers on a milder day.
Think less "new season wardrobe overhaul" and more summer, with a little more structure.
That is really the beauty of transitional dressing. You are not saying goodbye to summer. You are simply turning the volume down.
The trench coat earns its keep
Few pieces understand British weather quite like the trench coat.
It is light enough to throw over a T-shirt when the temperature is still hovering somewhere around pleasant, but substantial enough to deal with a chilly morning or an unexpected shower. It also has the useful ability to make an outfit look considered when you have spent approximately three minutes deciding what to wear.
This season, the classic trench is getting some interesting updates too. Alongside traditional silhouettes, AW26 has seen designers experiment with different proportions, materials, collars and details, giving the wardrobe staple a little more personality.
But you do not need to go dramatic. A well-cut trench in a neutral shade will work with denim, dresses, tailoring and pretty much everything else in your wardrobe.
When it rains, make a plan
There is no prize for pretending it isn't going to rain.
The smarter approach to transitional dressing is to have a few layers that can handle whatever the forecast decides to throw at you. A lightweight raincoat is one of those pieces you may not think about until you desperately need one, at which point you will wonder how you ever lived without it.
For practicality, look for styles that are roomy enough to wear over a jumper but light enough to fold away when the sun inevitably makes an appearance. For an AW26 style update, look for the oversized fits that are popular right now. A raincoat can also be surprisingly useful as an everyday layer, particularly when you want something more practical than a wool coat but more polished than a waterproof jacket.
And yes, it is worth checking the forecast before you leave the house. We have all learned this the hard way.
Layers are your best friend
If transitional dressing had a superpower, it would be layering.
Not five jumpers piled on top of one another. Just clever layers that can be added or removed without requiring an outfit change in the middle of the day.
Start with a simple base such as a T-shirt, shirt or lightweight top. Add a fine knit, cardigan or lightweight jumper, then finish with a jacket or coat. Suddenly, the same outfit can cope with a chilly commute, a warm café and the walk home.
The other advantage? Layers give an outfit more depth. A shirt collar peeking out from a jumper, a cardigan worn over a dress, or a jacket thrown over tailoring can make familiar pieces feel completely different.
This is also the perfect time to bring lightweight knitwear back into the rotation. Save the chunky jumpers for later. Right now, it is the finer, more versatile layers that earn their place.
The first boots moment
There is a moment every autumn when you look at your sandals and think: not today.
Maybe the morning is cooler. Maybe the pavement is wet. Maybe you simply feel that the time has come.
Whatever the reason, pulling on your first pair of boots after summer is one of the small pleasures of the season. Suddenly, an outfit that has felt very August starts to feel decidedly September.
Ankle boots are an obvious place to start. Wear them with a summer dress to give it a little more autumnal attitude, with jeans and a knit for an everyday combination, or with a skirt and bare legs while the weather still allows it.
And this autumn, boots do not have to mean sensible black. AW26 footwear trends are playing with everything from knee-high silhouettes to richer colours and more statement shapes.
Your jacket does not have to be a coat
One of the easiest ways to make your wardrobe feel more autumn-ready without overheating is to think beyond coats.
A jacket can do much of the work at this time of year. Think denim, suede, utility-inspired styles, tailored jackets or lightweight bombers. They add just enough warmth for cooler days without making you feel like you have dressed for January.
The AW26 runways are also giving jackets more personality, with everything from checks and funnel necks to more defined waists appearing across the season's collections.
Try one over a summer dress, with wide-leg trousers or simply thrown over jeans and a T-shirt. The result feels new-season without looking like you have tried too hard to make it so.
A little colour goes a long way
Autumn does not have to mean immediately retreating into black, beige and grey.
There are plenty of richer shades coming through for AW26, including deep navy, plum, powder blue and butter yellow. Navy in particular is having a strong moment, appearing across collections from Burberry to Ferragamo and Gucci.
But you do not need to commit to a head-to-toe new-season palette. Sometimes the most interesting approach is simply to introduce one unexpected colour into an otherwise familiar outfit.
Try butter yellow with chocolate brown. Powder blue with something deeper. Or, if you are feeling braver, take inspiration from the season's more playful approach to colour and put shades together that you would not instinctively pair. Pink and green, for example, are officially having a rethink.
Consider this the warm-up. We have plenty more to say about autumn colour combinations.
The real trick? Dress for the day, not the season
The best transitional wardrobe is not necessarily the one packed with brand-new autumn pieces. It is the one that gives your existing wardrobe more mileage.
Keep the summer dress. Add boots.
Keep the T-shirt. Add a cardigan.
Keep the skirt. Add a knit.
Keep the sandals nearby, just in case. Socks and Birkenstocks anyone?
And keep a trench coat or raincoat by the door because, in Britain, optimism about the weather is rarely a sensible styling strategy.
Transitional dressing is really about finding that sweet spot between the seasons. It is the moment when linen meets knitwear, bare legs meet boots and a summer favourite gets an entirely new lease of life.
And if that means bringing out the boots a little earlier than strictly necessary? We won't judge.
