How to Style a Workwear Outfit for UK Autumn: Technical Tips, Fabrics, Layers & Brands

Autumn in the UK brings a transitional wardrobe challenge—mornings can be brisk, midday temperatures might rise, and damp conditions are common. Mastering workwear for UK autumn requires balancing functionality with polish, comfort with structure, and style with practicality. Whether you're navigating a smart office dress code or a hybrid schedule, layering the right pieces is key.

This guide breaks down the technical components of styling the perfect UK autumn work outfit—fabrics, fit, cuts, colours, and brands that suit the season—plus how to find your perfect fit with Tellar.co.uk.

1. Understanding Autumn Dressing: The Technical Context

UK autumn spans mid-September through late November, with average temperatures ranging from 8°C to 17°C. Rain is frequent, and daylight hours gradually shorten.

Key technical challenges:

Varying indoor/outdoor temperatures
Damp air, frequent rainfall
Central heating and commutes
The need for easy layering

Your wardrobe needs to accommodate these fluctuations without compromising on professional standards.

2. Start with Smart Base Layers

Recommended Fabrics:

Merino wool: Naturally breathable, odour-resistant, and insulative
Cotton jersey or modal blends: Ideal for breathable blouses or long-sleeve tops
Silk: Lightweight yet warming; elegant for layering under blazers

Style tip: Choose a lightweight, fitted long-sleeve top as your core layer. Look for roll necks or scoop necks in neutral shades—charcoal, ivory, or navy. These allow easy pairing under suits or open cardigans.

3. Layer with Smart Knitwear

A structured knit offers both warmth and professionalism.

Autumn-Ready Options:

Merino or cashmere blend crew necks
Structured cardigans with clean lines
Knitted waistcoats or fine gauge vests

Avoid overly slouchy or chunky knitwear. Prioritise pieces that skim the body and layer well under tailored coats.

Best UK brands:

John Lewis Autograph
Arket (noted for sleek silhouettes and neutral tones)
Reiss (tailored luxury knitwear)
COS (minimalist, merino-rich staples)

4. Opt for Seasonal Trousers or Midi Skirts

For Trousers:

Fabric: Wool-blend, ponte, or heavy twill
Cut: Straight, cigarette, or wide-leg with sharp creases
Fit tip: Mid-to-high rise is most flattering for layering

Avoid linen or lightweight viscose which lose shape in damp weather. Look for trousers with a slight stretch for commuting comfort.

For Skirts:

Style: A-line midi skirts in heavier fabrics (wool, faux suede)
Pair with: Opaque tights (minimum 40 denier), loafers or ankle boots

Brands to consider:

Hobbs London for structured trousers
Boden for work-ready midi skirts
Me+Em for elevated tailoring

5. Blazers & Outerwear: Structure Meets Seasonality

Blazers:

Look for wool-blend or ponte knit blazers
Shoulder structure adds professionalism
Unlined or half-lined styles offer more breathability indoors

Key colours for autumn:

Charcoal, forest green, burgundy, warm taupe, rust, and navy

Autumn Coats:

Trench coats: Always a classic, ideally water-resistant
Wool-blend wrap coats: Professional and polished
Tailored overcoats: Longline styles in camel, navy or grey

Avoid: Puffer coats unless your office is ultra-casual

Top Outerwear Picks:

Massimo Dutti wrap coats
Mango wool blend belted coats
& Other Stories structured trenches
Jaeger (John Lewis) for classic British tailoring

6. Footwear for Wet Pavements & Polished Looks

Ideal Office Shoes:

Ankle boots (leather or waterproof suede, block heel)
Loafers with rubber soles
Brogues for a heritage touch
Mid-heel court shoes with enclosed toe

Avoid ballet flats (poor weatherproofing) or open-toe heels.

Brands for Autumn Footwear:

Russell & Bromley
Clarks
Dune London
Vagabond

Tip: Invest in leather protector spray and keep a spare pair of pumps at the office.

7. Layered Accessories for Warmth & Polish

Scarves: Choose lightweight wool or cashmere. Avoid bulky blanket scarves in formal settings.
Tights: Black opaque tights, ideally 60+ denier for warmth
Umbrella: Always have a compact one to hand
Tote bag: Consider waterproofed materials or lined leather bags

8. Smart Casual or Hybrid Workwear Looks

If your office allows for smart-casual dressing or you're working hybrid:

Pair a turtleneck with straight-leg jeans and a wool coat
Try midi shirt dresses layered with tights and Chelsea boots
A knit vest over a crisp white shirt is a contemporary hybrid outfit

Fabric to lean on: Tencel, modal, brushed cotton, ponte knit

Styling brands to try:

Whistles
Sezane (France-based, UK shipping)
Uniqlo (brushed thermals + tailored casuals)

9. Styling Guidelines by Body Shape

Hourglass: Emphasise waist with belted coats and high-waisted trousers
Pear-shaped: Opt for A-line skirts, structured blazers, and statement necklines
Rectangle: Use layers to add curves—drape, asymmetric knits, peplum blazers
Apple: Streamline the silhouette with longline coats and V-neck knits
