What’s My Clothes Size at Cefinn? Does Cefinn Run Big or Small?
Cefinn—founded by Samantha Cameron—is a modern British fashion label focused on elevated day-to-night dressing with clean lines, refined tailoring, and practical luxury. Its smart, work-ready pieces are designed to feel polished and comfortable in equal measure, with dresses, trousers and blouses that transition seamlessly from boardroom to evening event.
But with tailored silhouettes and premium fabrics comes the question:
Does Cefinn run big or small?
And how can you find your exact size before investing in timeless wardrobe pieces?
This post explains how Cefinn sizing works—by garment and fit type—and introduces Tellar.co.uk, the UK’s leading free sizing tool that calculates your correct Cefinn size in real time, based on your measurements and body shape.
Does Cefinn Run Big or Small?
Cefinn runs true to size overall, but with a tailored, close-to-the-body fit across most collections.
Structured dresses and fitted bodices can feel snug—especially in non-stretch fabrics
Shirts and trousers tend to fit close, without much ease through the torso or hips
Jersey pieces and relaxed styles are more forgiving and true to size
If you’re curvy, broad-shouldered, or between sizes, you may need to size up in fitted garments like panelled dresses, bias skirts, or buttoned shirts.
Why Cefinn Sizing Requires Precision
Cefinn designs are elegant and minimalist—but rely heavily on fit and construction to achieve their streamlined silhouette.
1. Tailoring-Led Design
Cefinn pieces often feature:
Darted waists
Seam panelling
Invisible side zips
Midsection contouring
This offers a flattering fit—but little give if your measurements fall between sizes.
2. Fabric Behaviour
Key fabrics used include:
Tech crepe – structured and fluid, but not stretchy
Silk twill – soft but close-fitting when cut on the bias
Wool blend tailoring – smart and polished, but may feel snug
Heavy jersey and ribbed knits – relaxed and easier to fit
If a garment uses crepe or viscose with no elastane, accurate size selection is critical.
Cefinn Fit Overview by Garment Type
Garment Type | Fit Style | Tellar Sizing Tip |
|---|---|---|
Tailored midi dresses | Fitted at waist/bust | Size up if busty or between sizes |
Bias-cut skirts | Slim at hip/waist | Size up for curves |
Smart trousers | High-rise, structured cut | Size up for hip room |
Silk blouses | True to size or narrow | Size up if broad-shouldered or busty |
Jersey tops & knits | Relaxed and forgiving | True to size or size down for a neat fit |
Shift/column dresses | True to size, clean cut | Stick to size unless curvy at hip |
Cefinn Size Chart (UK)
UK Size | Bust (cm) | Waist (cm) | Hips (cm) |
|---|---|---|---|
6 | 80 | 62 | 88 |
8 | 84 | 66 | 92 |
10 | 88 | 70 | 96 |
12 | 92 | 74 | 100 |
14 | 97 | 79 | 105 |
16 | 102 | 84 | 110 |
While Cefinn’s chart is a helpful baseline, it doesn’t account for:
Cut (tailored vs. relaxed)
Fabric behaviour
Your body’s proportions (e.g. pear-shaped, hourglass, athletic)
That’s why Tellar.co.uk offers a much more accurate solution.
