Author: Stylist at TellarDate: 2025
With its effortless Italian aesthetic and clean, contemporary tailoring, Semi-Couture brings a sense of understated sophistication to every wardrobe. Whether you're drawn to its flowing dresses, elevated knits or slouchy trousers, the pieces are made to last—and to stand out. But if you're new to the brand, you’re likely asking:
What size am I in Semi-Couture, and does it run big or small?
✨ tellar.co.uk helps you find your perfect fit in thousands of brands, including Semi-Couture. You’ll receive a free measuring tape, set up your profile once, and instantly get personalised, accurate size recommendations across every style. It’s always free. No size charts. No returns.
About Semi-Couture: Italian Cool Meets Everyday Ease
Born from Italian label Erica Cavallini’s fashion house, Semi-Couture captures the spirit of modern luxury with an unpolished edge. The name reflects the balance between craftsmanship and wearability—with every piece designed to feel elevated but not overdone.
What you'll find:
Easy tailoring in neutral tones
Relaxed trousers, wide-leg denim and soft knits
Layered midi dresses and oversized outerwear
A blend of structure and softness, with a silhouette-first approach
But with European sizing and intentional looseness, getting the right fit can be tricky—especially for UK shoppers. That’s where Tellar helps.
Is Semi-Couture True to Size?
Semi-Couture generally runs true to size—but its relaxed cuts, boxy shapes and non-stretch fabrics can make certain pieces feel oversized or, at times, slim through the waist or bust depending on your proportions.
Fit Summary:
Tops & shirts – relaxed, sometimes oversized
Dresses – true to size, with loose silhouettes
Trousers – fitted waist, often wide-leg or cropped
Knitwear – soft and forgiving
Jackets & outerwear – generous in shape, structured in shoulder
📏 Check your Semi-Couture size instantly using Tellar’s Store Size Lookup tool. It compares your actual shape to each garment’s construction—for the perfect match, every time.

Structured trousers may feel slim at the waist
Online listings rarely show full garment measurements
