What Is Sizing Like at Deus Ex Machina menswear?

Deus Ex Machina runs broadly true to size across its core range, but it is not a "one fit fits all" label. The cut shifts noticeably depending on what you're buying:

Tees and jersey — standard fit, neither slim nor oversized. Take your usual size.
Shirts and overshirts — a touch relaxed, built for layering.
Jackets and outerwear — genuinely roomy, cut for movement.
Trousers and boardshorts — true at the waist, relaxed through the leg.

So the honest headline is: buy your normal size, but pay attention to the category, because that's where people come unstuck (see: my overshirt).

Tees and jersey

This is where Deus is at its most dependable. The classic logo tees and the surf-and-moto graphics come in a proper middle-of-the-road cut — not clingy, not a tent. If you're a solid medium in Uniqlo or COS, you're a medium here. The cotton is a decent weight and softens rather than shrinks, so you don't need to buy a size up as insurance.

The one thing to watch: Deus occasionally drops boxy capsule cuts on limited or collaboration pieces, where the body is deliberately wider and shorter. Those aren't the norm, but if a tee looks unusually cropped in the product photos, read the description before you commit — a box fit and a regular fit can share the same size label.

Shirts and overshirts

Deus does a lovely line in flannels, workshirts and vintage-leaning overshirts, and these sit slightly relaxed by design. That's deliberate — they're meant to go over a tee or a bit of knitwear, or hang open as a light layer. Here's how I'd play it:

Wearing it buttoned and tucked? Your usual size is bang on.
Wearing it open, over layers? You've got room already, so resist the urge to size up unless you're properly broad.

The overshirts in particular are the sweet spot of the range — the piece I got wrong first time and now own three of.

Jackets and outerwear

This is the heart of the brand and the category that trips most people. Deus's canvas, twill and waxed cotton jackets are cut for mobility and warmth — the moto heritage is real, and a jacket you can't move your arms in on a bike is a useless jacket. So they run roomy on purpose.

My advice: take your true size and let the jacket do what it's designed to do. Only size up if you're planning to wear a chunky knit underneath through winter. Sizing up "for the look" is how you end up swimming in it.

Trousers, chinos and boardshorts

Bottoms are the most straightforward part of the range. The trousers and chinos are true at the waist with a relaxed, straight-ish leg — good news if you carry a bit through the thigh, less ideal if you want everything tapered to the ankle. The boardshorts, meanwhile, are reliably true to size; order your normal waist and you'll be fine.

How I'd style it

Deus works best when you lean into the workwear-meets-surf DNA rather than fighting it. A few directions that are landing well right now:

The clean moto casual look — a plain heavyweight tee, straight indigo denim, and a waxed overshirt. Understated, and it ages beautifully.
Faded and washed everything — the trend has swung hard towards soft, lived-in colour, and Deus's sun-bleached palette is made for it. Pair a washed-out tee with off-white or ecru trousers.
One graphic, kept quiet — let a logo tee or a printed shirt be the single loud item and keep the rest plain. Head-to-toe branding is the fastest way to look like a walking billboard.

Footwear-wise, keep it honest: worn-in leather boots, low-top canvas, or a chunky suede. Anything too polished fights the vibe.

Brands to wear alongside Deus

Deus is a mood as much as a label, and it plays beautifully with the wider heritage-casual, workwear and moto world. Here's who I'd build a wardrobe around it with, across three tiers — with a note on how each one fits compared to Deus, since that's the whole point.

High street

Levi's — the natural denim partner to Deus. The 501 is true to size but rigid, so factor in a little give; the slim and tapered cuts (511, 512) run leaner than Deus's relaxed leg, so size for how you actually want them to sit.
Superdry — the accessible route into Japanese-Americana graphics and light moto jackets. Runs a touch slim and short in the body compared with a Deus tee, so I'd often go up a size to get the same easy drape.
Timberland — for boots and heritage outerwear on a sensible budget. The jackets are roomy and layer-friendly in the same spirit as Deus's; just note the boots run large, so drop half a size.

Independent & boutique

Nudie Jeans — Swedish raw-denim specialists with a genuine sustainability streak. The cuts are slimmer and higher-rise than Deus, and the raw pairs stretch out roughly a size over the first month, so buy them snug.
Rogue Territory — an LA workwear atelier doing beautiful supima denim and chore jackets. Slightly more structured and trim than Deus's roomy heritage cut, so take your true size and expect a cleaner line.
Iron & Resin — spiritually Deus's Californian cousin: moto, surf and the open road. The fits are relaxed and vintage-inspired, so it sits closest of anyone here to a Deus fit — true to size, no surprises.

Designer & luxury

Rag & Bone — downtown New York with a moto-influenced edge and superb denim. Cut sharper and slimmer than Deus, so if you want that same relaxed ease you'll want to size up one.
John Varvatos — the rock-and-roll biker end of luxury, strong on leather and lean silhouettes. Runs slim and slightly short, so size up compared with your Deus size, especially in the tees.
Todd Snyder — elevated American heritage-casual, brilliant for taking the workwear look somewhere smarter. True to size but with a tailored-casual line that's a shade cleaner and slimmer than Deus.

Mix a tier or two and you've got a wardrobe with real character — a Deus overshirt over a Todd Snyder tee, or Nudie denim with a Deus jacket, and you're away.

The honest bit about buying this online

Here's the catch with everything I've just told you: fit "rules" are averages, and you are not an average. A brand can run true to size and still be wrong for your shoulders, your torso length, your particular build. That's exactly how I ended up with a Deus overshirt I had to send back — I trusted the vibe instead of the numbers.
