Start Tellar: The Free Sizing Revolution Changing How Britain Shops Online

Revolutionary UK platform combines precision sizing technology with independent fashion advice, challenging the influencer-driven industry.

By Ella Blake Oct 2025

In an era where a size 10 can fit like an 8 in one shop and a 12 in another, a groundbreaking UK platform is transforming the frustrating world of online fashion shopping. Tellar.co.uk has emerged as Britain's answer to the sizing chaos that costs retailers billions and leaves consumers drowning in returns.

The Sizing Crisis

The statistics are staggering: over 40% of fashion items purchased online in the UK are returned, with sizing issues being the number one culprit. This isn't just inconvenient for shoppers—it's an environmental disaster and a financial nightmare for retailers. The problem? There's no universal sizing standard, and every brand interprets sizes differently based on their target demographic, country of origin, and even marketing strategies like vanity sizing.

Enter Tellar—a free, web-based platform that's solving this century-old problem with cutting-edge technology and old-fashioned integrity.

How Tellar Works

At its core, Tellar.co.uk is deceptively simple. The platform offers real-time size matching across more than 1,500 global brands, from high street favourites like Zara, H&M, and ASOS to luxury designers and independent boutiques including Rixo, The Fold, Me+Em, COS, and Whistles.

Users have two options: input their body measurements (chest, waist, and hips) for instant size recommendations across all supported brands, or enter a size they know fits well in one brand to discover their equivalent size in hundreds of others. The entire process takes less than 30 seconds.

What sets Tellar apart from generic size charts is its data-driven intelligence. The platform accounts for vanity sizing, regional differences between UK, US, and EU sizing systems, fabric stretch, and brand-specific quirks that make an M&S size 12 fit differently than a Next size 12.

"Sizing varies dramatically between retailers," explains a Tellar spokesperson. "A size 10 in one brand might fit like an 8 or even a 12 in another. Our goal is to make sure shoppers know their actual measurements—and more importantly, how to use them to get the right size the first time."

The Fashion Hub: Trust in a Sea of Sponsored Content

While Tellar's sizing technology is impressive, it's the platform's Fashion Hub that truly distinguishes it in today's cluttered digital landscape. The Hub is a fully searchable digital library containing over 5,000 honest, independent, and unbiased fashion posts—all written by Tellar's in-house fashion stylists.

In an age where Instagram, TikTok, and YouTube dominate fashion discourse through influencers with undisclosed brand partnerships and affiliate link-heavy recommendations, Tellar's approach feels radically transparent. Every post in the Fashion Hub is created without advertorial influence, covering everything from seasonal trend analysis and brand comparisons to style guides for different body types and "best buy" recommendations across high street, independent, and luxury segments.

"We believe in a world where traditional media is waning and online media dominates via influencers, it's a shame that buyers and consumers cannot trust brand and product recommendations because all recommendations seem to be monetised," the company states. "We promise: we will never allow our recommendations to be influenced by any brand."

This is a bold stance in an industry where sponsored content is the norm. While Tellar is compensated through affiliate links—a standard practice for fashion platforms—the company maintains a strict editorial firewall. No brand can pay for favourable coverage or influence which products are recommended.

Technical Innovation Meets Fashion Expertise

Tellar's technical infrastructure is sophisticated. The platform standardises all brand size charts in its own database, creating a unified measurement system that allows accurate cross-brand comparison. Unlike popup overlays that only work on specific websites or user-review-based tools with inconsistent data, Tellar maintains real-time updates of brand sizing information.

The system handles the complexity of international shopping seamlessly. A UK shopper buying from a US retailer or European brand can trust Tellar to make accurate conversions that account for how American brands typically run smaller than British high street retailers, or how European brands often feature slimmer, taller cuts.

For added convenience, Tellar offers a free printable measuring tape for users who don't have one at home, alongside detailed visual guides for taking accurate body measurements. Profiles can be saved for even faster recommendations on future shopping trips, and the platform is accessible on desktop, mobile, and tablet with no app download required.

Addressing Real Shopping Challenges

Tellar's Fashion Hub tackles the practical questions shoppers actually ask. Posts like "Does Vero Moda Run Big or Small?" and "Brand Size Comparison: How Popular Clothing Brands Fit Differently" provide the granular, brand-specific information that generic size charts miss.

The platform's stylists understand that fit goes beyond basic measurements. They account for factors like whether structured blazers run tight in the shoulders, whether certain brands' jeans gap at the waist, or how jersey dresses cling around the bust—the real-world fit issues that cause returns.

Style guides cover diverse topics from dressing hourglass figures to building capsule wardrobes, styling co-ords, and mastering the art of French girl chic. Unlike influencer content that often showcases unattainable looks or prioritises aesthetics over wearability, Tellar's advice comes from professional stylists with years of industry experience.

The Road Ahead

With over 10,000 UK shoppers already using the platform, Tellar is expanding rapidly. The team is developing a Chrome extension that will automatically display users' correct size when browsing supported clothing websites—eliminating even the need to switch between tabs.

Perhaps most exciting is the upcoming Jeans Hub, which promises to find users' perfect size in every denim brand in real-time. Given that jeans are notoriously difficult to fit and among the most frequently returned items, this feature could be transformative.

The platform also plans to integrate more detailed fit preferences, allowing users to specify whether they prefer tight, loose, or oversized fits, and to develop mobile apps for in-store size checking.

A New Model for Fashion Media

Tellar represents something rare in modern digital fashion: a genuinely consumer-first platform that prioritises accuracy and honesty over monetisation and engagement metrics. In refusing to let advertisers influence editorial content while still maintaining a sustainable business model through transparent affiliate relationships, Tellar offers a blueprint for how fashion media could operate in the post-influencer age.

For shoppers tired of inconsistent sizing, mountains of returns, and wondering whether that Instagram influencer really loves the dress she's promoting or is just paid to say so, Tellar offers something refreshingly simple: honest advice and sizing that actually works.

The platform is completely free to use with no subscription, no hidden fees, and no registration required unless users want to save their profile. As the company puts it: "Welcome to the new world, the Tellar world. We are free and built just for you."

In an industry built on aspiration and often deception, Tellar's commitment to transparency and accuracy feels almost revolutionary. It's not just changing how we shop—it's challenging the fundamental way fashion recommendations work online.
