Autumn 2026 Outfit Ideas: The New Season Edit

There is a particular point in the year when getting dressed becomes a little less predictable.

Summer has not completely disappeared, but autumn is beginning to make itself known. Mornings feel cooler. Evenings arrive earlier. Sandals are still within reach, yet suddenly a cardigan does not seem like such a bad idea.

It is also one of our favourite times to get dressed.

Autumn does not have to mean putting away everything you wore through summer and starting again. The most useful wardrobes simply begin to evolve: a new layer here, a richer colour there, a printed dress worn differently.

At Yumi, our latest collection is doing exactly that.

The new season brings together statement knitwear, expressive prints, easy dresses, checks, richer colour and lightweight outerwear — pieces designed to work now and keep working as the temperature changes.

If you are wondering what to wear this autumn, consider this your starting point.

What Should You Wear Between Summer and Autumn?

The easiest answer is to think in layers rather than seasons.

During late August and September, you rarely need a full winter wardrobe. Instead, look for pieces that can adapt throughout the day:

midi and shirt dresses
lightweight cardigans
knitted waistcoats
blouses and long-sleeve tops
skirts with easy knitwear
wide-leg trousers
lightweight jackets

Start with an outfit that works while the weather is mild, then add one layer that you can put on or take off.

Yumi’s New In collection is currently built around exactly this kind of dressing, with new pieces arriving across dresses, knitwear, tops, skirts and outerwear.

1. Make the Midi Dress Your Autumn Starting Point

There is good reason the midi dress remains one of the hardest-working pieces in a wardrobe.

It gives you enough coverage for cooler days without feeling heavy while the weather is still mild, and it can move easily between work, weekends, dinners and occasions.

This season, we are particularly drawn to prints that feel a little richer than high-summer florals: deeper backgrounds, paisley, abstract patterns and earthy colour palettes.

The new Yumi collection includes brown paisley, darker florals, navy, teal and multicoloured prints alongside classic silhouettes such as wrap and shirt dresses.

For late summer, keep the styling simple with flats or trainers.

Then, as autumn arrives, add:

ankle boots
a cardigan
tights
a cropped jacket
a structured bag

One dress, several months of wear.

2. Rediscover the Cardigan

The cardigan is having a very good season — although, as far as we are concerned, it never really left.

What has changed is how much personality knitwear can bring to an outfit.

Rather than treating a cardigan purely as the practical layer you reach for when it gets cold, make it part of the look itself.

Our new season knitwear moves beyond simple basics with:

floral appliqué
contrast detailing
embroidery
textured finishes
statement buttons
richer autumn shades

A distinctive cardigan can transform even the simplest outfit.

Try one over a printed dress for a mix of pattern and texture, pair it with a skirt for an easy weekend look, or wear it with trousers and a blouse when you want something polished without feeling too formal.

3. Bring Florals Into Autumn

Florals do not need to disappear because summer is ending.

The secret is simply changing the palette and the styling around them.

Bright florals against light backgrounds naturally feel summery. Move towards deeper greens, burgundy, navy, black, teal and earthy browns and the same idea begins to feel completely at home in autumn.

You can also change the mood through texture.

A floral dress worn with sandals belongs to August.

The same dress with knitwear, boots and a jacket can move comfortably into October.

Our current newness includes florals appearing not only across dresses, but through embroidery, appliqué and intarsia knitwear too — allowing print and botanical details to become part of an autumn wardrobe rather than something reserved for warmer days.

If print is already part of your style, explore our floral dresses.

4. Add a Knitted Waistcoat

If there is one piece that makes sense when the weather cannot quite decide what it is doing, it is the knitted waistcoat.

Warm enough to add texture and interest, but without the weight of a full jumper, it is made for transitional dressing.

This season’s Yumi edit includes flower-appliqué knitted waistcoats and tanks in shades including burgundy, brown, teal and green.

Wear yours:

Over a crisp shirt

Perfect when mornings are cooler but you do not want a heavy layer.

With wide-leg trousers

An easy combination for work or weekends.

Over a dress

A useful way to change the shape and feel of a dress you already own.

With a skirt

Pair a textured knit with a checked or plain skirt and let the contrast do the work.

It is exactly the kind of piece that extends your wardrobe rather than replacing it.

5. Let Checks Signal the Change of Season

Some prints simply feel right when autumn arrives.

Checks are one of them.

The latest Yumi collection introduces brown and burgundy checks through skirts, trousers and outerwear, creating an easy bridge between summer dressing and the richer textures of the season ahead.

A checked skirt works particularly well with a simple knit or blouse. Add tights and boots later in the season and the same outfit continues working as temperatures fall.

Checked wide-leg trousers offer another route. Pair them with a tucked-in top now, then layer with knitwear once cooler weather settles in.

The trick with a statement check is to let it lead.

You do not need every element of the outfit to compete.

Explore our latest skirts and trousers to build the rest of the look around it.

6. Invest in a Lightweight Jacket Before You Need a Coat

September dressing rarely calls for a heavy winter coat.

A lighter jacket gives you far more flexibility.

This season, look for pieces you can comfortably layer over:

dresses
blouses
fine knitwear
shirts
skirts and tops

The new Yumi outerwear edit includes cropped silhouettes, boxy shapes, quilted styles and a cropped trench — exactly the sort of pieces that work when the weather changes several times in one day.

A shorter jacket also works particularly well with midi dresses and wider-leg trousers because it helps keep the proportions of the outfit balanced.

7. Look Beyond Traditional Autumn Colours

Autumn may be associated with brown, burgundy and forest green, but your wardrobe does not need to become completely muted.

The Yumi approach has always made room for colour.

This season, richer neutrals sit alongside:

teal
blue
red
pink
green
multicoloured prints

Think of autumn colour as deeper rather than duller.

Brown paired with teal feels different from brown paired with cream. Burgundy can work beautifully with pink. Green can sit next to navy. A colourful knit can be the easiest way to lift neutral trousers or a skirt.

If your wardrobe is normally quite understated, introducing one colourful piece is often enough.

You do not need to change your whole palette because the leaves have changed theirs.

8. Give the Shirt Dress More Than One Job

Few pieces move between seasons quite as naturally as a shirt dress.

Wear it alone while days are warmer, then gradually introduce layers.

A long-sleeve shirt dress can work with flats now and boots later. Add a cardigan when the temperature falls or define the waist with a belt for a more structured look.

The current Yumi collection includes new paisley and scarf-print shirt dresses in richer tones that feel particularly suited to this point between seasons.

It is an easy way to bring autumn into your wardrobe without feeling as though you have dressed for November in August.

9. Keep Some Pieces Playful

Practical autumn dressing does not have to mean sensible-looking clothes.

One of the strongest ideas running through our new knitwear is detail.

Flowers appear as embroidery, appliqué and knitted motifs. There are statement patterns, contrast borders and playful intarsia designs.

These are the pieces that make simple outfits memorable.

Wear an embroidered jumper with trousers.

Pair a flower-detail cardigan with denim.

Layer an appliqué knit over a shirt.

When the rest of your outfit is simple, one unexpected detail can be enough.

That balance between wearable and distinctive is at the heart of the new season Yumi collection.

How Do You Style Summer Dresses for Autumn?

Before you put your summer dresses away, look at them again.

Many can continue well into autumn with a few simple changes.

Try adding:

a cardigan over a midi dress
boots instead of sandals
tights as the temperature drops
a cropped jacket
a knitted waistcoat
darker accessories

Printed dresses are particularly adaptable because changing the colours surrounding the print can completely change their mood.

This is one of the easiest ways to make your wardrobe work harder — and to avoid treating every change in season as a reason to start again.

What Are the Best Colours for Autumn Outfits?

There is no single autumn palette, but richer tones naturally work well as the light and weather change.

For Autumn 2026, the Yumi new season edit is particularly strong in:

Brown — an easy alternative to black and particularly good with print.

Burgundy — rich without feeling overly formal.

Green — from deeper shades to brighter colour accents.

Teal — an easy way to bring colour into autumn dressing.

Navy — timeless, versatile and softer than black.

And because this is Yumi, plenty of colour and print remains alongside them.

The best autumn wardrobe should still look like your wardrobe.

What Are the Best Autumn Wardrobe Essentials?

You do not need dozens of new pieces to make the transition into autumn.

A useful starting wardrobe could include:

A printed midi or shirt dress
A statement cardigan
A lightweight jacket
A versatile skirt
A pair of wide-leg trousers
A blouse or long-sleeve top
A textured or embroidered knit

The best choices are pieces that connect with clothes you already own.

That gives you more outfits without needing more things.

What Should I Wear in September in the UK?

September style is about flexibility.

UK weather can move from surprisingly warm afternoons to cool mornings and wet evenings, sometimes all on the same day.

Start with a breathable base — a dress, blouse, skirt or trousers — and add a removable layer such as a cardigan or lightweight jacket.

Avoid dressing for the calendar.

Dress for the day.

That is what makes transitional pieces so useful.

The New Season, the Yumi Way

A new season does not need a completely new wardrobe.

Sometimes it is simply about finding a few pieces that change the way everything else works.

A cardigan over a favourite dress.

A new print.

A richer colour.

A lightweight jacket you can throw over almost anything.

A knitted waistcoat that makes an old shirt feel completely different.

This autumn, the Yumi collection is full of those pieces: distinctive enough to bring personality, versatile enough to earn their place in your wardrobe.

And perhaps that is the best way to approach the season ahead.

Not by dressing for every trend.

By finding new ways to dress like yourself.
