Does Dondup Clothes Brand Run Big or Small? A Complete Sizing Guide + Best Items to Buy

Dondup, the contemporary Italian fashion label known for blending heritage denim craftsmanship with modern tailoring, is quickly gaining popularity among fashion-forward consumers. But with its luxury Italian roots comes an inevitable question: Does Dondup clothing run big or small? If you’ve been eyeing their premium denim, tailored jackets or minimalist knitwear but aren’t sure about sizing, this in-depth guide will tell you everything you need to know.

From fit insights to the best pieces to invest in, plus how to match your measurements to Dondup sizes using Tellar.co.uk, this pillar guide is your one-stop-shop for Dondup sizing clarity.

Who Is Dondup?

Founded in 1999 in Fossombrone, Italy, Dondup is a premium ready-to-wear label initially rooted in high-end denim. Over the past two decades, the brand has expanded into full menswear and womenswear collections, offering everything from elevated basics to standout tailoring.

Dondup is known for:

Italian-made quality and precision tailoring
Innovative dyeing and wash techniques
Clean, modern lines balanced with utilitarian influences
Strong sustainability commitments

Their seasonal drops often merge military inspiration with minimalism—making it a go-to for wardrobe staples that last.

Does Dondup Clothing Run Big or Small?

In general, Dondup runs small, particularly compared to standard UK or US sizing. This is typical for many Italian brands, where the cut is more tailored and designed for a slimmer fit.

Here’s a breakdown by category:

Denim (Jeans and Trousers): Run small by ½ to 1 full size. Their jeans often have a slim to skinny silhouette with a mid-to-low rise. Size up if you're in between sizes or prefer a more relaxed fit.
Jackets and Blazers: Tailored and narrow through the chest. If you have broader shoulders or a fuller bust, you may need to size up.
Knitwear & T-Shirts: Tend to fit true to size but with a fitted shape. Size up for a looser or layered look.
Shirts and Blouses: Often cut slim with high armholes and minimal ease. Consider sizing up for comfort, especially in cotton poplin shirts.

How to Convert Dondup Sizes to UK Sizes

Dondup uses Italian sizing, which can be confusing if you're used to UK/US standards. Here’s a basic conversion:

For Women:

IT 38 = UK 6
IT 40 = UK 8
IT 42 = UK 10
IT 44 = UK 12
IT 46 = UK 14

For Men (Trousers/Denim):

IT 44 = 28” waist
IT 46 = 30”
IT 48 = 32”
IT 50 = 34”
IT 52 = 36”
IT 54 = 38”

But even with conversion tables, fit can vary by collection, cut, or fabric. That’s why it's better to match clothing to your exact measurements — and this is where Tellar.co.uk becomes essential.
