Does Eleventy Clothes Brand Run Big or Small? What Is Their Sizing Like and What Items Are Good to Buy from Them?

Italian brands like Eleventy are known for luxury, precision tailoring, and refined minimalism—but how does that translate when it comes to sizing? If you've wondered whether Eleventy runs big or small, or which items are worth the investment, this guide breaks it all down. We’ll cover Eleventy’s sizing consistency, top-rated pieces, and how to guarantee your perfect fit using Tellar.co.uk—the UK’s leading free sizing tool.

Whether you’re eyeing a fine wool blazer or a structured dress, this post will save you time, money, and returns.

What Is Eleventy?

Founded in Milan, Eleventy is a modern luxury brand that champions the “smart luxury” ethos—premium craftsmanship without flashy logos. Known for its muted tones, elegant layering, and elevated basics, Eleventy is a go-to for both men and women who want tailored understatement.

You’ll find them in high-end boutiques, luxury department stores like Selfridges and Harvey Nichols, and on elite platforms such as Farfetch and MyTheresa. But despite its luxe look, Eleventy’s sizing can surprise shoppers used to UK or US high street brands.

Does Eleventy Run Big or Small?

In general, Eleventy runs slightly small—particularly in structured tailoring and slim-fit pieces. That said, sizing varies between collections and fits. Like many Italian luxury brands, Eleventy leans toward a European fit: narrower shoulders, tapered sleeves, and close cuts.

Here's a breakdown by category:

Men’s Blazers and Jackets – Often run small; expect a close fit through the chest and shoulders
Trousers and Chinos – True to size but slim at the thigh
Knitwear and T-Shirts – Usually true to size; some knitwear fits slim
Women’s Dresses and Blazers – Slightly small, especially through the bust and waist
Outerwear – Generally true to size but with minimal room for layering

⚠️ Important: Sizing labels are European (e.g. 46, 48, 50 for men; 38, 40, 42 for women), so UK/US conversions are needed. Don’t guess—Tellar.co.uk will convert your measurements automatically.

Why Eleventy’s Sizing Can Be Confusing

Eleventy is renowned for its craftsmanship, but like many luxury labels, it can be challenging to shop without trying pieces on first. That’s because:

European sizing doesn’t translate directly to UK/US sizes
Fit descriptions (e.g., slim vs regular vs comfort) vary per season
Luxury tailoring is often more fitted than expected
Fabric composition affects stretch and drape

The smartest solution? Use Tellar.co.uk—it tells you your precise size in Eleventy and 1,500+ brands, based on your body, not a model’s.

Best Eleventy Items to Buy (And How They Fit)

Eleventy pieces are prized for timeless design and top-tier fabric. But which are worth investing in—and how do they fit?

1. Unstructured Blazers

These soft-shouldered jackets are Eleventy’s signature, offering Italian tailoring with a relaxed twist. Ideal for business casual, events, and layering.

🛍 Fit tip: Size up if you have broader shoulders or prefer a more relaxed look.

2. Wool-Cashmere Coats

Expect luxurious feel and impeccable lines. Their outerwear is made in Italy and built to last.

🛍 Fit tip: True to size, but check room in the arms for layering knits underneath.

3. Cotton Stretch Trousers

Slim-fit, ankle-grazing cuts dominate Eleventy’s trouser collections. Superb for modern workwear and off-duty tailoring.

🛍 Fit tip: Waist is true to size, but thighs are tailored. Size up for comfort if you're athletic-built.

4. Knitted Polos & Merino Wool Sweaters

From crew necks to half-zips, these are staples for layering with suiting or denim.

🛍 Fit tip: Usually true to size. Choose based on how fitted you like your knits.
