Wednesday’s Girl Size Guide: How to Find Your Perfect Fit and What’s Worth Buying

Author: Stylist at TellarDate: 2025

Wednesday’s Girl is a fashion-forward favourite on ASOS, delivering trend-led dresses, casual co-ords, and curve-loving cuts—all with that effortlessly feminine vibe. But while their styles are accessible, their sizing often isn’t.

If you've ever ordered a floaty Wednesday’s Girl tea dress in your usual size only to find it too tight or too loose, you're not alone.

That’s where tellar.co.uk steps in—the UK’s Leading Free Sizing Tool, helping you find your best fit in over 1,500 brands, including Wednesday’s Girl, based on your actual body measurements.

Why Wednesday’s Girl Sizing Can Be Hit or Miss

While Wednesday’s Girl offers everything from petite to plus-size options, the sizing still varies massively across:

  • Dress styles (wrap vs. smock)
  • Bodycon vs. oversized fits
  • Curve vs. Standard vs. Tall categories
  • Different retailers listing their own versions

Even if you know your UK size, that’s often not enough. Bodycon might need a size up. A smock might drown you. And trousers? Don’t even start.

🧠 That’s why tellar.co.uk was created—so you never have to second-guess your size again.

How to Find Your Size in Wednesday’s Girl in Seconds

All you need are three simple body measurements—chest, waist, hips—and Tellar instantly calculates your best-fitting size across the entire Wednesday’s Girl range, based on how the brand actually fits.

How Wednesday’s Girl Clothes Really Fit

Here’s a breakdown of the most popular categories, and how they tend to fit on real customers.

👗 1. Dresses

Their signature piece. From wrap to midi to smock, the dress is where sizing struggles most often appear.

👚 2. Tops and Blouses

Expect a mix of floaty and fitted styles. Here’s what you need to know:

  • Sizes are labelled in UK 6–18 (some items go up to UK 24+)
  • Sleeve lengths can run long on petite figures
  • Chest and shoulder fit can be tight for fuller busts

🧠 Pro tip: If you often struggle with bust sizing, Tellar uses your actual chest measurement to recommend the right size by garment type.

👖 3. Skirts, Shorts and Bottoms

This is where most customers hit problems—especially when buying online without trying on.

  • Many styles have fixed waistbands with no stretch
  • Some skirts use elastic only at the back, causing inconsistent sizing
  • Shorts often sit high and can pinch at the waist if you’re curvy
