Does the Brand Roberto Collina Run Big or Small? What Is Their Sizing Like & What’s Worth Buying?

Roberto Collina is an Italian label renowned for quietly luxurious knitwear, premium tailoring, and architectural silhouettes.

But for many first-time shoppers, one question lingers: Does Roberto Collina run big or small?

📌 Here’s what you need to know:tellar.co.uk lets you match your exact measurements to Roberto Collina—and thousands of other brands worldwide. Our brand count is growing daily. You’ll also get a free measuring tape posted to you. No size charts, no confusion—just your perfect fit in seconds.

What Defines the Roberto Collina Aesthetic?

As one of Italy’s most respected knitwear labels, Roberto Collina is known for:

Premium merino, mohair, cashmere, and alpaca yarns
Modern cuts with subtle tailoring
Refined basics: rollnecks, polos, cardigans, and crewnecks
Neutral palettes and monochromatic styling
Runway-ready outerwear in minimalist silhouettes

Every piece is manufactured in Italy and designed for longevity—but the fit tends to follow a continental block, which can feel smaller than UK standards, especially in the shoulders, chest, and sleeve length.

So, Does Roberto Collina Run Big or Small?

In general: Roberto Collina runs slightly small, particularly in structured knits, slim tailoring, and shirts. However, relaxed-fit jumpers and boxy silhouettes run true to size.

For Knitwear (Jumpers, Polos, Rollnecks):

Slim through the shoulder and torso
Often with ribbed cuffs and hem for tailored shape
Fit tip:Size up for a looser fit, or if layering over shirts

For Outerwear (Coats, Zip Jackets, Bombers):

Tailored fit through chest and arm
High armhole placement for Italian cut
Fit tip:Size up if between sizes or layering over knitwear

For Trousers:

Mid-to-high rise
Trim through thigh and tapered at ankle
Fit tip:True to size in waist, but snug in seat/thigh—size up if athletic build
