Aspesi is one of Italy’s most understated luxury labels — known for minimalist design, technical outerwear, and beautifully crafted basics. But if you’ve browsed their famous field jackets or tailored shirts online, you’ve likely asked the same question many do:
“Does Aspesi run big or small?”
In this detailed guide, we’ll unpack how Aspesi sizing works across categories, what to expect as a UK shopper, and how Tellar.co.uk helps you find your perfect fit instantly — for free — across Aspesi and 1,500+ other premium and high-street brands.
About Aspesi: Timeless Italian Design Meets Function
Founded in 1969 by Alberto Aspesi, the brand originally specialised in men’s shirts before becoming known for its functional, military-inspired outerwear and sleek, neutral-toned separates.
Today, Aspesi is stocked at high-end retailers like Matches, Mr Porter and Harrods, and favoured by minimalists who appreciate craftsmanship over logos. But Aspesi’s sizing, rooted in Italian tailoring standards, can feel confusing to UK or US shoppers.
So, Does Aspesi Run Big or Small?
Short answer: Aspesi runs slightly small in tailored and outerwear pieces, and true to size in relaxed or knitwear items.
Here’s a detailed breakdown:
| Category | Sizing Fit |
|---|---|
| Jackets & Coats | Slightly small – structured, tailored fit |
| T-shirts & Knitwear | True to size – relaxed but not oversized |
| Shirts | Slim fit – may run small in shoulders or chest |
| Trousers | True to size, but slim in hip/thigh |
| Dresses | Structured through waist and bust – may need to size up |
| Padded Vests | Fitted – especially across chest |
Aspesi’s garments reflect Italian sizing norms, which favour slim, close-to-the-body silhouettes. If you’re used to UK high street or American brands, you may find some items run narrow across shoulders and shorter in length.
What Customers Say About Aspesi Fit
At Tellar.co.uk, we collect detailed user insights based on real body data and customer experiences. Here are some frequent remarks regarding Aspesi sizing:
-
“The quality is amazing, but the jacket ran tight across the back”
-
“I’m usually a UK 10, but the shirt felt like an 8 — size up if you want movement”
-
“Their down vests look clean but size up if you have a bust”
-
“Slim sleeves and tight buttons on the tailored shirts”
Most feedback highlights the same theme: Expect slim, tailored silhouettes, and consider sizing up for comfort — particularly in woven fabrics and outerwear.
How Aspesi Compares to Other Brands
If you’re new to Aspesi, it helps to compare their fit to more familiar UK or EU labels:
| Brand | Fit Comparison |
|---|---|
| COS | Aspesi is slimmer and more tailored |
| Massimo Dutti | Similar quality, but Aspesi is cut closer to the body |
| Reiss | Comparable in structure, but Aspesi can be smaller in the chest |
| Barbour | Aspesi jackets are less boxy, more European in silhouette |
| APC | Aspesi fits similarly through shoulders, slightly tighter in arms |
So if you’re used to looser cuts or more casual European brands, you may want to size up when shopping at Aspesi — especially in coats, shirts, or structured trousers.
Why Size Charts Aren’t Enough
Aspesi provides traditional EU sizing, but that doesn’t always translate well for UK shoppers. Here’s why size charts fall short:
-
They don’t adjust for cut or silhouette (e.g. slim fit vs relaxed)
-
They don’t show how the fabric behaves (e.g. no stretch vs soft jersey)
-
They often lack bust/hip guidance for women’s styles
-
No guidance for body types outside sample-size models

When to Size Up in Aspesi
Based on Tellar’s data and brand-specific insights, we recommend sizing up in the following Aspesi categories:
-
Field Jackets – classic M65 styles are snug at the shoulders
-
Slim-Fit Shirts – especially those in poplin or stretch cotton
-
Tailored Dresses – structured cuts leave little room for curves
-
Gilets / Padded Vests – can compress across bust or back
In contrast, T-shirts, jersey dresses, and lightweight knits tend to fit true to size and may not need adjustment.

Final Thoughts: Aspesi = Timeless Style, But Slim Fit
