Autumn may be knocking, with its soft golden light, cool-edged evenings and a hint of colour in the leaves, but that doesn’t mean it’s time for your summer wardrobe to go into hibernation. September is that in-between time when Summer is waving goodbye, but Autumn hasn’t quite unpacked its suitcase yet and it calls for a wardrobe refresh, rather than total transformation. 

This month is all about transitional dressing: light post-summer layers, mood-boosting colours and practical pieces that will see you through unpredictable weather. Forget the full-on chunky knit leap into winter, we’re talking warm yet airy fabrics, luxe accessories and clever layering so you can embrace autumn’s charm without losing that end-of-summer spirit. 

If you’re wondering where to start with September styling, we’re on hand with some autumn-friendly ideas. 

1, Boho dresses for everyday ease 

If there’s one hero piece to reach for this September, it’s the boho dress. Loose, flowing shapes keep things comfortable, while earthy prints and soft fabrics bring a little warmth as the days start to cool. Opt for long sleeves or three-quarter sleeves so you’re covered when the breeze picks up but they’re still light enough to wear with sandals on a warmer afternoon. 

The beauty of boho dresses is their versatility. Team them with ankle boots and a denim jacket for weekend strolls, or add a tailored blazer and statement earrings for a relaxed but put-together workday look. 

Best boho style dresses for autumn 

  • Sophie Lilac Dress – this floaty number will carry you right through the last days of summer. Made from breathable cotton, it’s got three-quarter length sleeves for just the right amount of coverage, and a soft, pretty pattern. 

  • Greta Floral Long Dressautumn’s all about colour, and this dress keeps things vibrant and cheery, even after the sun’s gone in. It’s got pockets for practicality and rolls up small, ideal for any late-summer travels. 

2, Shirt dresses and tunics to make layering simple 

A crisp shirt dress or an easy tunic is perfect for those what’s-the-weather-doing mornings. Worn alone, they’re a nod to the last of the summer sun. But layer them over leggings or skinny jeans, or add a lightweight cardigan or a kimono, and you’ve instantly got a cosier, autumn-ready outfit. 

Look for styles in deeper jewel tones think teal, mustard or burgundy to give your look a seasonal update without losing vibrancy. Cinch the waist with a woven belt to add shape and texture, and you can transform your silhouette. 

Best shirt dresses and tunics for autumn 

  • Lori Tunic – blend retro charm with cross-season practicality – and bring a splash of colour to your day at the same time. The shorter length works well over leggings or skinnies while the long sleeves give you welcome coverage as the air begins to cool. 

  • Eloise Scarf Tunic – the simple, rustic print and modern boat neckline of this tunic top lends itself beautifully to autumn style. Wear over jeans with a belt to create shape and you’ve got an outfit that’ll take you right through the season. 

Lightweight scarves for dopamine dressing 

Accessories are your secret weapon when it comes to transitional dressing, and nothing lifts an outfit like gorgeous scarves. They add a pop of colour, a dash of pattern and a touch of luxe without weighing you down. There are so many ways to style a light scarf, wear a silky one knotted loosely around your neck, tied in your hair, or even looped through your belt or handbag strap for a playful twist. Or go for a longer version for a little more coverage with just as much style. 

Choose bold florals or geometric prints to keep your outfits feeling fresh and upbeat – the perfect antidote to grey skies. 

Best scarves for autumn 

  • Rosie Floral Scarf – available in gorgeous ochre, burgundy or dusty pink colourways that are all perfect for autumn, this longer scarf adds a touch of warmth while still staying fresh. 

  • Sienna Square Scarf – silky against your skin, stylish to the eye. This square scarf is ideal for wearing as an oh-so-elegant neck tie or twisting through your hair for endless summer vibes.
