What Is Sizing Like at Marc O’Polo? A Stylist’s Honest Fit Guide

In short: Marc O’Polo generally runs true to size on the top half but slightly snug at the waist, so if you carry your shape on your hips or you’re between sizes, I’d size up. It’s a Swedish-German label built on relaxed Scandinavian tailoring and lovely natural fabrics, which means the fit is forgiving in jersey and knits but more precise in anything woven or structured. Get those two rules straight and you’ll rarely send a parcel back.

So how does Marc O’Polo actually fit?

I’ll be honest – the first Marc O’Polo piece I ever bought was a linen-blend shirt in my “safe” size and I sized it the way I would a high-street tee. Rookie error. The body was beautifully relaxed (that signature Scandi ease), but the sleeves were clearly cut for someone a good few inches taller than my 5ft5in. It taught me everything I now tell clients about this brand: the cut is generous through the body and arms, but length favours taller frames.

Here’s how it breaks down across the categories I get asked about most:

Tops & shirts: Classically tailored rather than slim. Roomy across the chest and shoulders, with a relaxed drape. Lovely if you like a softer line; size down only if you genuinely want it fitted.
Knitwear & jersey: The most forgiving category by a mile. Stretch and drape do the work, so your usual size will almost always behave.
Trousers & chinos: The one to watch. The waist runs small, especially in low-stretch and woven fabrics. Measure your waist and your hips before committing.
Dresses: Jersey styles are easy-going; woven or structured ones can pull narrow at the shoulders and bust. Fuller-busted? Go up a size and let it skim.
Coats & jackets: Cut with a touch of room for layering, but check the shoulder if you’re planning to wear a chunky knit underneath.

A quick word on their sizing system

This trips people up constantly. Marc O’Polo mostly uses EU numerical sizing (think 34, 36, 38 and up), but a chunk of the casualwear lands in standard S–XL, and menswear leans into continental numbers like 48, 50, 52. So the “size” on the label genuinely shifts depending on which rail you’re standing at. My advice: ignore the label number and work from your body measurements every single time. Their own guidance even says that if you’re between sizes, go up – which tells you everything about how snug the smaller size really is.

Styling Marc O’Polo so it earns its keep

This is a brand that rewards a quiet, considered wardrobe rather than a trend-led one. The pieces are investment basics – the kind of thing you reach for on a Tuesday and still love three winters later. A few things I’d steer you towards:

Lean into the relaxed shoulder on shirts by tucking loosely into a straight-leg trouser – it reads “effortless” rather than “oversized.”
Their natural fabrics (linen, cotton, fine merino) take a leather belt and good gold jewellery beautifully. Let the clothes stay neutral and let an accessory do the talking.
For trousers, if the waist nips but the leg is perfect, a tailor’s small waistband adjustment costs less than a coffee-and-cake and saves the piece. I do this constantly.

Where else to shop if you love the Marc O’Polo look

If that relaxed, fabric-led, Scandi-adjacent aesthetic is your thing, here’s where I’d send you across the price spectrum.

On the high street

COS – the closest spiritual cousin: minimal, architectural, gorgeous fabrics. Runs slightly oversized, so size down for a sharper line.
White Stuff – soft, easy-wearing naturals with a friendlier price tag and a generous, true-to-size cut.
Seasalt Cornwall – brilliant for organic-cotton casuals and that lived-in, coastal ease; fit is relaxed and reliable.
Boden – dependable everyday quality, true to size, and strong on the smart-casual middle ground.
Hush – effortless wardrobe staples in lovely jersey and linen; a touch generous, so size down if you’re between.
Jigsaw – quietly elegant tailoring and knitwear with a grown-up sensibility very close to Marc O’Polo’s.
Massimo Dutti – continental polish and beautiful fabrics; cut is slim, so this is the one to size up in.
Mint Velvet – relaxed luxe with great drape; true to size and made for layering.

Premium

Whistles – clean, contemporary tailoring with a modern edge; reliably true to size.
Reiss – sharper and more structured; a smart step up when you want a defined silhouette.
Me&Em – clever, elongating cuts that flatter without fuss, and genuinely thoughtful about proportion.

Luxury & designer

Max Mara – the gold standard for camel coats and quiet luxury; an investment that lasts decades.
Totême – the Scandi minimalism dialled all the way up: pared-back, expensive-looking, endlessly wearable.

Two off-the-radar independents worth knowing

Mads Nørgaard – a Copenhagen indie with that exact relaxed Scandi DNA and a cult following for its soft, easy separates.
Albaray – a smaller British label doing responsible, fabric-led smart-casual that feels like a quieter, conscience-friendly Marc O’Polo.

The honest takeaway

Marc O’Polo is a brand to buy with your measurements in hand, not your assumptions. Trust the relaxed body, respect the snug waist, mind the long sleeves – and you’ll build a wardrobe of pieces that quietly outlast everything else you own. It’s never flashy, and that’s precisely the point.
