Does the Brand Barba Run Big or Small on Clothes Sizing?

Introduction: Barba Napoli and the Art of Italian Menswear

Barba Napoli—often referred to simply as Barba—is one of Italy’s most respected luxury shirtmakers. Founded in Naples, the brand is rooted in sartorial excellence, blending traditional craftsmanship with modern style. Barba is known for precise tailoring, premium cottons, and timeless pieces ranging from shirts and trousers to full suits.

But one common issue for first-time buyers—especially those shopping online—is sizing.

So does Barba run big or small on clothes sizing?

In this guide, we break down Barba's fit across its key product lines, share feedback from UK customers, and explain how tellar.co.uk removes the uncertainty by giving you your exact size across Barba and 1,500+ other brands.

Barba Napoli Sizing at a Glance: Tailored, Slim, Traditional

Barba’s sizing reflects its Neapolitan tailoring heritage, which means garments are generally designed for a close-to-the-body fit, especially in the torso and shoulders.

Item Type	General Fit Description
Formal Shirts	Slim, Fitted – Runs Small
Casual Shirts	Slightly Slim – True to Size
Trousers	Tailored – True to Size or Slim
Jackets & Blazers	Slim-cut – Often Run Small
Knitwear	Relaxed or True to Size

Summary: Barba is not a vanity sizing brand. Expect a European slim fit, and if you’re used to UK high street or American brands, you may need to size up, especially in dress shirts.

Shirt Fit Options: What Barba Offers

Barba shirts come in three main cuts, which affect how the garment sits on the body:

Classica Fit
- Traditional cut
- More generous in chest and waist
- Best for those with a broader frame
- Comparable to a regular fit in British brands
Slim Fit
- Most common cut sold online
- Tapered waist, high armhole
- Ideal for athletic or lean builds
- Comparable to Reiss or Hugo Boss slim shirts
Super Slim Fit (Skinny)
- Very tailored, almost custom fit
- Narrow shoulders, close-fitting collar
- Designed to be worn tucked and pressed

How Barba Shirts Compare to UK Brands

Brand	Fit Comparison to Barba
TM Lewin	Barba is slimmer, more tailored
Charles Tyrwhitt	Barba is more structured & fitted
Reiss	Similar in Slim fit
Paul Smith	Slightly roomier than Barba

International Sizing: EU vs UK in Barba

Barba uses EU/IT sizing, typically by collar size in cm, for shirts. This can confuse UK shoppers used to S/M/L or inches.

Use this size conversion guide:

Barba Size (cm)	UK Collar (inches)	General Size
37	14.5	Small
38	15	Small–Medium
39	15.5	Medium
40	15.75	Medium–Large
41	16	Large
42	16.5	Large–XL

Important: Due to slim tailoring, many UK shoppers will need to go up one collar size to accommodate shoulder and chest width.

Customer Feedback: What UK Buyers Say About Barba Fit

Real-world reviews help build a clearer picture:

“The craftsmanship is stunning, but the 15.5” fit more like a 15. I had to size up.”
“I love the fabric and the cut, but these are definitely made for slim builds.”
“Excellent tailoring, but I recommend sizing up if you lift weights or have broad shoulders.”

Most agree that Barba’s strength is also its challenge: high-end Neapolitan tailoring is very exacting, and unless you’re already used to this style, it may feel small.

Trouser and Blazer Fit in Barba

Barba trousers and blazers reflect the same design DNA:

Trousers: Slim through the thigh and seat. Expect a tailored, narrow leg.
- If you're athletic or curvy in the hips, size up.
- Minimal stretch in most fabrics.
Blazers & Jackets: Traditional Neapolitan shoulder, close-cut chest, and often short length.
- Designed to hug the body, not drape it.
- Size up if layering or wearing over shirts with thicker fabric.

Your body shape (broad shoulders, narrow waist, etc.)
How different fabrics and styles behave
Brand-specific tailoring tendencies (like Barba’s slim arms)

That’s where tellar.co.uk changes everything.
