What Is Sizing Like at Aubin?

Does Aubin Run True to Size?

Aubin is a true-to-size to slightly relaxed brand, and it's cut for a real bloke's body rather than a 19-year-old model's. If you're an honest medium in most British high street shops, an Aubin medium will land where you'd expect on the chest and shoulders. The house cut is "regular with room to breathe" — not slim-fit, not boxy, but a considered middle ground that drapes well and lets the fabric do the talking.

That said, "true to size" is doing some heavy lifting there, because a few categories behave differently. Let's break those down, because this is where the returns happen.

Where Aubin's Fit Catches People Out

Overshirts and shackets: These are cut generously on purpose — they're meant to layer over a tee or fine-gauge knit. If you size down expecting a fitted shirt, you'll be disappointed (see: me, above). Take your normal size and enjoy the room.
Knitwear: The chunkier lambswool and Shetland-style pieces are relaxed through the body and a touch long in the sleeve, which is intentional for a roll-back cuff. If you like knitwear neat, this is the one place I'd consider sizing down — but only if you're between sizes.
Shirts and rugby tops: These run closest to true regular fit. A medium is a medium.
Chinos and trousers: Honest waist sizing, but the leg is a classic straight rather than a tapered slim. If you want a cleaner line at the ankle, factor in a quick tailoring trip or expect a relaxed break.

The single most useful habit you can build: stop guessing per category and start measuring once. More on that shortly.

How I'd Style Aubin Right Now

The whole point of a brand like this is unfussy, lived-in layering, and that happens to be exactly where menswear is heading this season. The hard tailoring obsession has softened; everyone's leaning into texture, earthy tones and pieces that look like you've owned them for years.

My go-to Aubin formula:

The overshirt as the hero. Cord or moleskin overshirt, plain crew tee underneath, straight-leg trousers, suede boots. It's the smart-casual uniform that never lets you down — and because the overshirt is cut roomy, it works open as a light jacket.
The rugby shirt, styled grown-up. Forget the sporty connotations. Worn under a gilet or with the collar up over a roll-neck, it's one of the most underrated pieces in British menswear this year.
Earth-tone knitwear over a collar. A flash of shirt collar peeking out of a crew-neck jumper is the easiest way to look put-together with zero effort. Olive, rust, oatmeal — these are the colours doing the work in 2026.

What to actually buy if you're starting from scratch? Begin with one overshirt, one piece of decent knitwear and a pair of straight chinos. That's a fortnight of outfits sorted, and every piece earns its keep.

Brands That Sit Well Next to Aubin

Aubin doesn't have to live alone in your wardrobe. If you like its heritage-casual lean, here are the brands I'd point you towards across three budgets — and crucially, how their fit compares, because that's half the battle.

High street

Crew Clothing — The closest high street cousin to Aubin's coastal-British feel. Fit is similarly regular and true to size, so if you know your Aubin shirt size, you're in safe territory here. Great for chinos and rugby-style tops at a friendlier price.
Fat Face — Relaxed, casual and built for weekends. Runs slightly generous, so consider your usual size rather than sizing up. Solid for casual knitwear and easy layering pieces.

Independent & boutique

Universal Works — Nottingham-based and brilliant at workwear-inspired separates. Cut a touch boxier than Aubin, so check measurements rather than assuming a like-for-like swap. The overshirts and pleated trousers are superb.
Wax London — Modern British label doing the textured-knit-and-overshirt thing beautifully. Fits true to size with a clean, contemporary line — slightly sharper than Aubin's relaxed cut, which is handy if you want a neater silhouette.

Designer & luxury

Private White V.C. — Made in Manchester, properly built outerwear and knitwear. Fit is tailored and true, so where Aubin gives you room, Private White gives you precision. Worth it for a forever coat.
Margaret Howell (MHL) — The gold standard for understated British design. Cut relaxed and generous — arguably even roomier than Aubin — so don't be tempted to size up. Investment pieces that genuinely last decades.

The pattern you'll have spotted: every one of these brands cuts slightly differently. Which is exactly the problem Tellar exists to solve.

Stop Guessing Your Size — Across Every Brand

Here's the honest truth as a stylist: the biggest reason men give up on good clothes is bad fit and the faff of returns. Aubin runs roomy on overshirts, neat on shirts; Universal Works is boxier; Margaret Howell is roomier still. Holding all that in your head is impossible. So don't.

MORE FROM THE HUB

Aubin is a brand I happily recommend — proper British clothes that reward a bit of knowledge. Get the fit right, lean into the relaxed pieces, and let the fabrics age into your wardrobe. And next time you're tempted to size down on an overshirt because of "winter weight"? Don't. Trust me on that one.
