Which Luxury Brands Run Large and Which Run Small? A Sizing Guide for Smarter Shopping

Shopping luxury fashion should be a seamless experience—yet for many, it's riddled with uncertainty around fit and sizing. Unlike high street retailers that often adopt standardised UK sizing ranges, luxury labels use proprietary sizing frameworks, different country origins (French, Italian, American), and bespoke tailoring philosophies. The result?

You could be a size 38 in one designer, a 42 in another, and a Medium elsewhere—all without changing body shape.

This guide explores which luxury brands tend to run small or large, why these discrepancies exist, and how Tellar.co.uk helps you navigate these fit inconsistencies with confidence.

Why Sizing Differs in Luxury Fashion

Luxury brands operate differently from mass-market brands in several ways:

• Heritage and origin: French and Italian sizing tends to run smaller than UK or US equivalents.

• Target demographic: Slimmer fit models and tailored silhouettes dominate the luxury space.

• Design intent: Many luxury brands prioritise form-fitting or fashion-forward silhouettes, not necessarily comfort or mass-market fit.

• Lack of vanity sizing: Unlike high street fashion, luxury brands rarely inflate garment dimensions to flatter consumers.

These factors make fit knowledge essential before investing in premium pieces—especially when shopping online.

How to Interpret Sizing (UK vs EU vs US)

Before diving into individual brands, it’s important to understand general size conversions:

However, these conversions are merely theoretical. Actual fit differs by brand—which is why a size 40 in Dior may not fit the same as a 40 in The Row or Gucci.

Additional Considerations When Shopping Luxury

1. Fabric matters

• Non-stretch silk, wool, and cotton blends will fit tighter than garments with elastane or viscose.

• Structured tailoring typically runs smaller than draped knitwear.

2. Garment category

• Blazers and trousers tend to have less sizing flexibility than t-shirts or dresses.

• Eveningwear is often more fitted than daywear collections.

3. Country of manufacture

• Italian and French sizes are often smaller by default than UK sizing.

• US brands tend to allow for slightly more ease through the hip and bust.

4. Style intent

• Consider whether the designer intended a piece to be body-conscious or relaxed.

• Oversized tailoring may look too big on a hanger but fit exactly as designed when worn.

Final Thoughts: Luxury Sizing Isn’t Standard—But It Can Be Decoded

In the luxury sector, no size chart tells the full story. Each designer approaches silhouette, construction, and target consumer differently—meaning fit will always vary across collections and seasons.

To make informed purchasing decisions—especially for investment pieces—knowing how each brand cuts its garments is crucial. And with platforms like Tellar.co.uk, you no longer have to guess.

Tellar lets you shop luxury confidently—whether you’re browsing Maje, sizing up in Dior, or selecting a Totême coat.
