Does the Brand OSKA Run Big or Small? What Is Their Sizing Like

Known for its artful silhouettes, sculptural layering, and slow-fashion values, OSKA is a favourite among those who seek style with ease and integrity. Whether it’s a pair of wide-leg trousers or a soft A-line tunic, OSKA’s pieces are designed with intention. But if you’re shopping online, one thing’s not always clear: Does OSKA run big or small?

🧵 Tellar.co.uk matches your measurements to OSKA’s sizing—and thousands of other brands. You’ll receive a free measuring tape, complete a one-time setup, and get your perfect size recommendation every time you shop. It’s always free, and it works for life. No guesswork. No size charts.

This guide explores how OSKA fits, how it compares to UK sizing, what to watch out for when shopping their collections, and which pieces are most worth your investment.

About OSKA: Sculptural Fashion With a Timeless Rhythm

Founded in Germany, OSKA focuses on design-led simplicity—producing clothing that balances structure and softness, strength and femininity. Its key design values include:

Oversized or boxy cuts
Sustainable production in Europe
Natural fibres like cotton, linen, wool, and jersey
Fluid silhouettes that don’t follow seasonal trends

With a focus on comfort and creativity, OSKA garments often appear oversized—but the sizing system still needs care to avoid fit errors, especially with layering pieces, trousers, and jackets.

So—Does OSKA Run Big or Small?

OSKA runs generously by design, especially in tops, tunics, and dresses. However, trousers, jackets, and structured pieces can run true to size or slightly small—particularly if you have a curvier shape.

General Fit Overview:

Tops, tunics, knitwear – oversized and relaxed
Trousers – true to size at waist; often roomy through thigh
Jackets and coats – structured shoulder, may feel narrow if layering
Dresses – A-line or boxy; roomy fit but variable length
Jumpsuits & overalls – wide through body, may run short in torso

🧵 Tellar’s Store Size Lookup gives you accurate OSKA sizing—calculated using your bust, waist, hips, height and desired layering preferences.

Why OSKA Sizing Can Be Confusing

OSKA is known for intentionally relaxed and sculptural fits—but product descriptions often lack precise fit information. This makes it tricky if you’re:

Between sizes
Petite or tall
Unsure whether the oversized shape will overwhelm your frame
Hoping to avoid excessive returns

That’s where Tellar.co.uk makes all the difference. We don’t rely on guesswork. We use real size data, fabric behaviour, and cut structure to recommend the best size for you—not just the best guess.

🎁 And yes—we send you a free measuring tape, so you only need to measure once.
