What Is Sizing Like at Carhartt WIP? A Stylist's Honest Fit Guide

So, Does Carhartt WIP Run Big or Small?

Big. Comfortably, deliberately big. The whole point of workwear is room to move and room to layer, so almost everything in the range carries a boxy, relaxed silhouette as standard. That's not a flaw — it's the look. But it does mean you need to be deliberate about which size you pull, and that depends entirely on the silhouette you're chasing.

The single most useful thing I can teach you is to read the fit label before the size label. Carhartt WIP tells you exactly what you're getting if you bother to look:

OG Fit — the original, and the widest, boxiest cut they make. Maximum volume.
Loose / Relaxed Fit — generous through the shoulders and body, often with a dropped shoulder or longer hem.
Regular Fit — the middle ground; roomy but not a tent.
Balloon Fit — loose through the leg or body with a boxier waist, big on their cargo trousers.

Jackets & Overshirts

This is where Carhartt WIP runs largest. The Detroit and Michigan chore jackets are cut boxy with wide arms, specifically so you can stack a hoodie underneath. If that streetwear-meets-workwear layered look is what you're after, take your normal size. If you want something neater you can wear over a shirt with chinos and leather shoes, size down one — I've done exactly that with a Detroit and it transformed it from "skip" to "tailored." Just know you lose the layering room.

Trousers

The clever bit: the waist is generally true to size, but the leg is cut loose. The Sid Pant is your slim-fit option, the Single Knee and Regular Cargo are properly roomy through the thigh. Order your actual waist measurement and let the leg do its thing. A confession — early in my career I sized a client up "to be safe" in a pair of cargos and he needed a belt to keep them on a waist that was already correct. Lesson learned: trust the waist number.

T-Shirts & Hoodies

Tees are boxy and longline compared to your average UK high street top — true to size if you like that relaxed drape, size down for a cleaner profile. Hoodies and the Chase sweatshirt run thick, structured and long in both body and sleeve. They're heavy, brilliant quality, and they soften beautifully — but if you want a standard fit rather than oversized, drop a size.

What to Buy and How to Style It

If you're starting from scratch, build around the chore jacket. It's the most versatile piece they make — sling it over a plain tee and tapered trousers in summer, layer it under a wool overcoat in winter. Keep the palette earthy: their hamilton brown, wall, dark navy and black do most of the heavy lifting. The current mood in menswear is very much utility-led — boxy outerwear, wider trousers, a softer shoulder — so Carhartt WIP is bang on trend without you having to try too hard. Cuff your trousers to break cleanly over a chunky boot or a low-key trainer and you've got a genuinely modern silhouette.

Brands to Pair With Carhartt WIP

Carhartt rarely lives alone in a wardrobe — it plays beautifully with a few neighbours. Here's where I send clients across three tiers, with a different reason for each:

High Street

Uniqlo — the U line gives you bombproof, well-cut basics for pennies. Perfect for the plain tees and merino layers that sit under all that workwear without competing with it.
Arket — Scandi-clean trousers and knitwear that share Carhartt's muted palette. The fits are slightly trimmer, so they balance the boxiness up top.

Independent / Boutique

Universal Works — Nottingham-based, workwear at its core, but with a softer, more grown-up cut. Their Bakers jacket is the natural step up from a chore coat.
Albam — quietly excellent British label doing understated, hard-wearing staples. Brilliant overshirts and sweats that won't shout over your Carhartt.
Norse Projects — Danish, considered, slightly more refined silhouettes. Their tees and outerwear bridge the gap between street and smart effortlessly.

Designer / Luxury

Stone Island — for when you want technical outerwear with proper presence. The fabric innovation is unmatched and it layers over a Carhartt hoodie like it was designed to.
Acne Studios — Scandinavian luxury with an oversized sensibility that speaks the same language as WIP. Their trousers and knit elevate a casual fit instantly.

Mix tiers freely — a Uniqlo tee, Carhartt trousers and a Stone Island overshirt is a genuinely great outfit, and nobody can tell which bit cost what. That's the whole game.
