Does the Brand M&S Autograph Run Big or Small on Clothes Sizing?

What Is M&S Autograph? The Premium Line from Marks & Spencer

Autograph is one of the most premium in-house labels from Marks & Spencer (M&S), offering elevated wardrobe essentials with a focus on luxury fabrics, refined tailoring, and modern design. While M&S is known for dependable fit and high-street accessibility, Autograph is its more fashion-forward, design-conscious counterpart—featuring higher-end materials like silk, cashmere, and Italian wool blends.

But when it comes to sizing, shoppers often ask:

Does M&S Autograph run big or small?

Despite M&S’s long-standing reputation for consistent sizing, Autograph garments can vary, especially in tailoring, outerwear, and fashion-led fits. Let’s break it down.

General Overview: Does M&S Autograph Run True to Size?

In most cases, Autograph runs true to M&S's standard sizing, but fit nuances differ depending on garment type and fabric.

Tailored pieces (blazers, trousers) may feel slimmer than standard M&S.
Relaxed garments (knitwear, loungewear) often run slightly larger.
Dresses and blouses are generally true to size, but structured or non-stretch styles can be less forgiving.

Summary:

Category	Fit Tendency	Advice
Tailored Blazers	Slim cut	May need to size up
Knitwear	Generous	Consider sizing down
Dresses	True to size	Follow standard UK sizing
Trousers	Structured fit	Check waist & hip carefully
Outerwear	Layered cut	Usually true to size

How M&S Autograph Sizes Compare with Other Brands

Unlike some high-street competitors like Zara or Mango, M&S (and by extension Autograph) sticks closely to UK sizing conventions. That said, Autograph’s premium styling—such as high armholes, slim sleeves, or tailored waists—can make the same size feel snugger than in other M&S sub-brands like Per Una or Goodmove.

“I’m a UK 12 in standard M&S, but the Autograph blazer in size 12 was tight across the shoulders—needed a 14 for comfort.” – JohnLewis.com review

Fit by Category: Detailed Breakdown of Autograph Sizing

1. Blazers and Tailored Jackets

Autograph is known for clean-lined, slightly masculine-inspired tailoring. Many pieces use wool blends or structured cotton, which means less stretch.

Cut slim, especially across shoulders and arms
Designed for a sharp silhouette
Some styles include light shoulder pads or double-breasted fronts

Sizing Tip: Size up if you’re broad-shouldered or plan to layer. Size down only if you prefer a close, sculpted fit with thin underlayers.

2. Knitwear and Cashmere

Autograph’s knits, particularly in merino wool, cashmere, and alpaca blends, are cut with a slightly relaxed silhouette, especially in boxy or drop-shoulder designs.

Roomier in the body
Ribbed hems may hug more tightly
Drop sleeves give a casual drape

“Autograph knitwear is beautiful but generous. My usual M&S 14 was quite oversized in the jumper—reordered a 12 and it fit perfectly.”

Sizing Tip: Size down for a more polished or fitted look. Stay true to size if you prefer a cosy, slouchy aesthetic.

3. Dresses and Occasionwear

From silky midi dresses to smart shirt dresses, Autograph styles are refined and true to M&S sizing. However, stiffer fabrics or tailored seams (like in shirt dresses or crepe styles) may feel snug.

Stretch styles are forgiving
Structured styles require precision in bust/waist fit
Zips and seams may limit flexibility

“The satin midi was elegant but tight around the waist—wish I sized up. The jersey dress was much easier to wear and true to size.”

4. Trousers and Skirts

Autograph trousers lean toward smart tailoring and include modern updates like cropped flares or paperbag waists.

High-waist designs often fit accurately at the waist
Hip and thigh fit can vary depending on the cut (slim vs wide leg)
Autograph sizing here is less forgiving than other M&S collections

Style Type	Sizing Behaviour	Recommendation
Slim Fit Trousers	Fitted through leg	Size up if between sizes
Wide Leg	Generous at hip	True to size
Pencil Skirts	Firm through hip	May need to size up

5. Outerwear

Autograph coats and trench coats are usually roomy enough for layering, especially those with dropped shoulders or raglan sleeves.

Wool coats and belted trenches: true to size
Technical puffers: slightly oversized
Light jackets: true to M&S size guide

“Autograph’s long coat was beautiful and warm. I’m a size 10 and the 10 fit perfectly, even with a jumper underneath.”

Real Feedback from Autograph Shoppers

“Autograph trousers are more fitted than M&S’s usual cut. If you’re curvy, size up—waist fits fine, but hips can be snug.”
– M&S customer review

“The quality is amazing—feels like Reiss but half the price. I stick to my usual size but avoid tailored cuts unless I size up.”
– Trustpilot user

“Knitwear runs big, but in the best way. My cashmere jumper is soft and stylish, but I could’ve gone down one size.”
– Fashion forum comment

Why Sizing Still Feels Confusing Across Brands

Even with reliable sizing charts, customers often struggle with:

Variations in cut or silhouette
Fabric behaviour (stretch vs non-stretch)
Individual body proportions (bust vs waist vs hip)
Whether a garment is meant to be relaxed, fitted, or structured

And even within the M&S family, Autograph sizing can differ subtly from other collections—which is why Tellar.co.uk exists.
