JDY (Jacqueline de Yong) is a stylish, affordable womenswear brand from the Bestseller group—alongside names like Vero Moda and ONLY. Known for trend-driven pieces at accessible prices, JDY is a go-to for everyday fashion. But when it comes to sizing, things can quickly become confusing.

If you’ve ever ordered JDY online and ended up with the wrong size—too tight in the hips, too loose in the shoulders—you’re not alone. The reason? Like many brands, JDY’s sizing is inconsistent across categories and often uses European standards that don’t always translate neatly into UK sizing.

At Tellar.co.uk, we take the guesswork out of sizing. Our free sizing tool lets you find your best-fitting size in JDY and over 1,500 other fashion brands—all in seconds.


Why JDY Sizing Can Be Difficult

JDY uses EU sizing labels (e.g. EU 36, EU 38, EU 40) but sells primarily to UK and global customers. That leads to several common problems:

  • Vanity sizing: Some JDY items run large or small to flatter the consumer.

  • Inconsistent fits: Dresses may be tighter than trousers, and jackets looser than tops.

  • Lack of standardisation across Bestseller brands (Vero Moda, ONLY, etc.).

That’s why we created Tellar.co.uk, the UK’s leading free sizing tool—built to recommend the correct size for JDY based on your actual body shape.


How to Find Your JDY Size with Tellar.co.uk

2. Get a Personalised JDY Size Recommendation

Once your profile is set up, our system compares your data against real size charts and fitting information for JDY. You’ll instantly see:

  • Your exact JDY size (e.g. EU 38, UK 10)

  • Size equivalents in other brands like ASOS, Zara, or H&M

  • Whether JDY runs small, large, or true to size for you

It’s far more accurate than relying on generic charts or guesswork.


3. Use the Store Size Lookup Tool

Need to check your JDY size at any time? Just visit the Store Size Lookup page and type in “JDY”. You’ll get your recommended size along with fit notes specific to each category—dresses, trousers, jackets, and more.

What’s Worth Buying from JDY?

Based on user reviews and purchase data, these are the best investments in the JDY range:

1. JDY Blazers

Their oversized blazers offer excellent structure and are on-trend season after season. Size down if you prefer a snugger fit—or use Tellar for a tailored recommendation.

2. JDY High-Waisted Jeans

Affordable, flattering, and great value. But they can run tight at the hips, especially in sizes EU 36–40. Tellar matches your waist/hip ratio to avoid sizing issues.

3. JDY Shirt Dresses

An office-to-weekend staple. These tend to fit tighter at the bust and waist, so it’s worth double-checking your measurements through Tellar’s profile tool.

4. JDY Knitwear

Chunky cardigans and jumpers are some of the brand’s best pieces. Generous in size—great for layering—but avoid going too oversized by using Tellar’s recommendations.


JDY vs Other Brands: Where It Sits

JDY fits differently from other Bestseller labels. Compared to:

  • Vero Moda – JDY runs slightly more relaxed

  • ONLY – JDY is truer to size in knitwear, but tighter in denim

  • Zara or H&M – JDY is more consistent but can still vary by product line

Use the Tellar.co.uk Store Lookup to compare how JDY sizing compares across these brands.
