At a Glance: Does JW Anderson Run Big or Small?

Based on Tellar.co.uk’s data, product reviews, and customer feedback, here’s the breakdown:

JW Anderson generally runs large or oversized — intentionally so.
Many pieces are cut with loose silhouettes and dropped shoulders, which are part of the brand’s design DNA.
However, certain items like knitwear, denim, or collab pieces (e.g. Uniqlo x JW Anderson) run smaller or more fitted.
Women’s sizing is often generous, while men’s cuts skew long and relaxed.

💡 Tip: The brand plays with proportion and structure, so it’s important to check the cut, fabric, and collection line (e.g. JW Anderson vs JW Anderson x Uniqlo).

What Size Should You Get in JW Anderson?

Regular JW Anderson Sizing (Runway/Mainline):

Women’s tops, dresses, and coats = run large or oversized
Structured trousers = true to size at the waist, looser in leg
Menswear = roomy shoulder, long arms, often boxy or drop-shouldered
Accessories (like bags) = true to listed dimensions, often larger in person

JW Anderson x Uniqlo Collaboration:

Fitted cuts, often run small compared to standard Uniqlo sizing
Women’s pieces may feel tight at bust/shoulders — especially blouses or smocks
Trousers = shorter rise and tighter fit than JW Anderson mainline

“The trench coat was huge — sleeves down to my knuckles. Loved the shape, but definitely needed to size down.”

“I’m a UK 10 and bought the JW Anderson x Uniqlo smock in Medium — far too tight at the shoulders.”
— Verified profile match user

“Love the androgynous style but trousers were roomier than expected. Waist true to size though.”

Key Items from JW Anderson: What to Buy?

1. Statement Outerwear

JW Anderson’s trenches, oversized bombers and cape-sleeve coats are consistently in demand.

Designed oversized — sleeves and length tend to run long
Look for pieces marked “boxy fit” or “drop shoulder” — these run up to two sizes larger than standard UK sizing
If you prefer a close fit, size down one or two sizes

3. Trousers and Denim

JW Anderson’s bottoms tend to be more structured:

Tapered, pleated, or flared cuts that assume a flat front and mid-to-high rise
Waist = true to size
Leg = often exaggerated, extra-wide or cropped high

📐 If your hips are proportionally wider than your waist, Tellar factors that into its personalised fit logic.

Final Thoughts: Is JW Anderson Sizing Reliable?

It depends — and that’s the point.

JW Anderson’s fit philosophy is intentionally subversive. From exaggerated coats to slouchy knits, the sizing often runs large or oversized. But when the fit does matter — like in structured trousers or collabs — it may run smaller than expected.

So don’t guess. Let Tellar.co.uk take care of it.
