Confused by Shein Couture sizing? Discover how their new luxury line fits vs UK sizes. Use Tellar to find your perfect size in thousands of brands.

Shein Couture, the brand’s new elevated and more premium fashion offering, blends runway inspiration with body-conscious silhouettes and more structured tailoring. It’s a significant step up from standard Shein ranges—but with better materials and more form-fitting cuts comes a more pressing question: What size am I in Shein Couture?

📌 Short answer:tellar.co.uk instantly matches your real measurements to Shein Couture—and thousands of brands, with new ones added daily. You’ll also receive a free soft tape measure. So you never have to rely on charts or guesswork again.

What Is Shein Couture?

Shein Couture is Shein’s newest premium capsule—positioned between high-street and designer. It features:

Sleeker materials: satin, mesh, tailoring-grade crepe
More structured silhouettes: corsetry, boning, sculpted bodices
Higher price points and limited-edition releases
Less stretch, more detail, and a greater focus on fit precision

That makes it fashion-forward—but also far less forgiving than regular Shein pieces.

So, Does Shein Couture Run Big or Small?

In general: Shein Couture runs small, especially in the bust, waist and hips. If you're used to relaxed Shein sizing, this range is much more fitted.

👗 Dresses

Structured mini and midi styles
Corset bodices, off-shoulder cuts, or boned seams
Fit tip:Size up if you’re fuller-busted, curvy or between sizes

👚 Tops & Bodysuits

Often cropped, sheer, or sculpted
Designed for a tight silhouette
Fit tip:Runs small in shoulder and chest—Tellar matches your exact fit

👖 Skirts & Trousers

High-waist, minimal-stretch, crepe or satin
Fitted through hip and thigh
Fit tip:Use Tellar to check waist-to-hip fit

🧥 Outerwear

Draped trenches, cropped boleros, fitted blazers
More accurate to size than other pieces
Fit tip:True to size, but snug if layering
