Coats – What Type Should I Buy for a Smart or Workwear Look vs Casual Wear?

Choosing the right coat is about more than just weather protection—it's about structure, proportion, purpose, and fit.

Smart & Workwear Coats: Structure, Sophistication, and Durability

In professional or formal settings, your coat should reflect authority, attention to detail, and polish. Beyond style, smart coats require thoughtful fabric selection, cut, and proportion control.

1. Wool Overcoats

Best for: Business meetings, formal events, daily workwear

Top brands:

Jigsaw – structured with longer lengths
Reiss – tailored, high-end finishes, runs slim
Hobbs – classic British cuts, more generous through hips
Massimo Dutti – elegant and structured, but tight at the shoulders

Fabric Fact: Wool and wool-blend coats offer superior insulation and drape. Look for options with at least 70% wool content for warmth and longevity.

Fit Tips:

The shoulder seam should align with your shoulder bone
Ensure there's enough room for layering a blazer underneath
Length should hit mid-thigh or lower for a formal silhouette

Avoid:

Ill-fitting sleeves (too long or short diminishes the structure)
Bulky shoulders if you have a petite frame—opt for slim lapels and lighter wool blends

tellar.co.uk – input your shoulder, chest, and hip measurements to get precise recommendations per brand.

2. Tailored Trench Coats

Best for: Spring/autumn workwear, commuter coats, smart layering

Brands to try:

Burberry – iconic, but slim through shoulders
Hobbs – elegant and flattering with UK-specific cuts
Zara – stylish but sizes vary widely by collection
Marks & Spencer – consistent sizing, especially in petite and tall

Style Advice:

Belted trenches define the waist and suit hourglass and rectangular shapes
Choose a storm flap and shoulder tabs for structure, especially on narrow frames
Go for water-resistant cotton blends or gabardine for functional durability

Avoid:

Belted trenches if you're short-waisted—opt for cropped or belted higher
Unlined options for cold climates; they lose structure

3. Crombie Coats

Best for: Winter businesswear, formal events, layering over tailoring

Strong brands:

COS – minimalist, clean lines
Club Monaco – refined, tailored
Whistles – contemporary fit, works for tall and curvy shapes
Joseph – luxe, true-to-size for structured coats

What to Look For:

A strong collar and single-breasted front for timeless structure
Knee-length for maximum versatility
Navy, charcoal, or camel for professional polish

Avoid:

Double-breasted options if you're broad-chested
Thin wool blends that sag with time

Use tellar.co.uk to avoid shoulder squeeze and sleeve misfits, especially for brands like COS or Reiss that run slim in upper arms.

Casual Coats: Flexibility, Warmth, and Day-to-Day Style

Casual coats balance comfort, wearability, and personality. Unlike smart coats, these allow more room for texture, colour, and laid-back structure—but fit still matters.

1. Puffer Coats

Best for: Cold casual wear, commuting, outdoor activities

Best brands:

The North Face – runs true to size but boxy
Uniqlo – lightweight puffers with slim profiles
Arket – chic, oversized fits for taller builds
Superdry – sporty with a more sculpted waist

Fit Strategy:

Cropped puffers flatter petite and hourglass frames
Long puffers with cinched waists work for apple and pear shapes
Choose hoods and storm cuffs for added functionality

Avoid:

Boxy puffers if you’re curvy without waist definition
Overfilled down unless you’re dressing for extreme cold

Check best puffer fits for your measurements with tellar.co.uk – shoulder width and waist alignment matter most here.

2. Parka Coats

Best for: Winter casual wear, daily errands, dog walking

Popular brands:

Barbour – heritage style, traditional British cuts
Canada Goose – premium, warm, but heavy
ASOS – trend-focused, variable sizing
Next – well-priced with reliable UK fits

Technical Tip:

Look for parkas with a waterproof shell and fleece lining
Faux fur hoods add warmth but can overwhelm smaller frames
Waist drawstrings can tailor an otherwise straight cut

Avoid:

Overly long parkas on petite frames
Bulky hoods if you have a short neck or narrow shoulders

tellar.co.uk and avoid trial-and-error purchases.

3. Teddy & Borg Coats

Best for: Fashion-led casual looks, transitional months

Great brands:

& Other Stories – oversized, high-pile styles
Urban Outfitters – cropped, trend-forward
Topshop – petite-friendly cuts
H&M – broad sizing but inconsistent per style

Fit Tips:

Works well on tall, straight or athletic frames
Choose single-breasted to avoid excess volume on fuller busts
Keep the rest of your outfit slim to balance proportions

Avoid:

Oversized teddy coats if you’re curvy or short—they can engulf your frame
Low-quality poly-blends that flatten quickly

Use tellar.co.uk to filter which cuts suit your chest and hip ratio for fleece or pile coats.

Body Shape Recommendations

Hourglass: Belted trenches, wrap coats, peacoats

Rectangle: Padded shoulders, waist-cinching coats, cropped puffers

Apple: Longline parkas, single-breasted overcoats, straight trenches

Pear: Structured top halves—Crombies, padded shoulders, A-line wool coats

Petite: Cropped puffers, trench coats with vertical seams

Tall: Oversized teddy coats, longline coats, double-breasted pieces

Don’t rely on brand labels alone. tellar.co.uk matches coat styles by fit and body shape—not just tag size.

Why Coat Sizing is So Inconsistent

Across UK and international brands, coat sizes vary due to:

Fit model variation – some use petite or tall base patterns
Vanity sizing – high-street brands may over-label sizes for sales
Style intent – oversized vs fitted can skew expectations
Fabric thickness – thicker linings can reduce inside space

Examples:

Burberry coats run slim across shoulders and bust
Zara sizing fluctuates dramatically depending on cut
Arket and COS favour boxy silhouettes
H&M often lists oversized items as regular sizing

That’s why a UK 10 in one coat may be too tight or too loose depending on the brand and construction.

Final Thoughts
