I’m Already In Autumn Mode: 7 Elegant Outfit Ideas I’ve Just Added to My Moodboard

It might seem a bit odd to even mention autumn while we’re in the middle of a heatwave; however, knowing how unpredictable the weather can be here in the UK, it’s never a bad time to start thinking about the chic outfits we’re going to wear when the temperature inevitably drops. I’ve personally already started to save outfits that I’ve spotted on my favourite Instagram influencers, with plans to recreate them when the autumnal season comes around. And I must admit, they have me wishing away the warmer days and looking forward to the change of season.

For autumn 2025 specifically, fashion people are focusing on creating looks that still feel elevated and chic, but with a touch of ease. Think oversized chunky knits paired with trendy barrel-leg trousers or sophisticated slip skirts worn with a relaxed car coat. It’s all about looking classy and refined whilst feeling effortless, something that I’m sure we all want to emulate this season.

If you, too, are looking for autumn outfit inspo that exudes equal parts ease and elegance, keep scrolling, as I’ve rounded up seven outfit ideas to re-create in the upcoming autumn season.

7 Elegant Outfit Ideas I’ve Added to My Autumn Moodboard

1. Jumper + Barrel-Leg Trousers + White Accessories

Style Notes: Chocolate brown has my heart again this autumn, and I’m planning to re-create this pairing of the chunky crew-neck jumper and barrel-leg trousers as soon as I possibly can. Add some contrasting leather accessories to break up the brown, and you’ll be set.

2. Car Coat + Slip Skirt + Strappy Heels

Style Notes: When it’s too early to pull out your wool coats, a car coat will do the trick for that ‘in-between’ weather. Dress up this relaxed style with an elegant slip skirt and strappy heels, and finish off the look with some sleek sunnies to give the outfit an ‘off-duty model’ vibe.

3. Trench Coat + Jeans + Ankle Boots

Style Notes: A trench coat is a London-girl staple, and as Marina (pictured above) proves, it doesn’t need much to make it look stylish. A simple white tee, a pair of light-wash jeans, and some black ankle boots are enough to let this timeless staple do the talking.

5. Blazer + Wide-Leg Trousers + Ballet Flats

6. Striped Jumper + Midi Skirt + Loafers

Style Notes: I've been all about skirts this year, and this definitely isn’t changing for autumn. However, unlike the billowy white skirts I opted for in summer, I’m now looking to deeper colours like charcoal grey to fit the mood of the season. Take a cue from Annabel (pictured above) and style the more structured skirt with a striped chunky knit and soft suede accessories.

Shop the Look:

Topshop

Knitted Fluffy Stripe Relaxed Polo

We can't get enough of Topshop's relaunch.

Reiss

Layer your knit over a relaxed tee.

Doesn't this look so expensive?

7. High-Neck Jumper + Satin Trousers + Leopard Slingbacks

Style Notes: When jeans feel too casual, fashion people turn to satin trousers that feel just as comfy but can also be dressed up for more formal occasions. Pair a rich brown shade with a classic white roll-neck jumper and then add some leopard shoes for a touch of fun.
