Does Jack Murphy Run Big or Small? A Honest Sizing Guide

By Ella Blake – Fashion Stylist | Tellar Fashion Hub – Always honest, unbiased & unsponsored

Jack Murphy runs large — particularly in its Heritage range, which is intentionally cut with extra room for layering. If you're buying a cape, a field coat, or any piece from the Heritage collection, you should seriously consider sizing down. The Standard range (shirts, fleeces, lighter jackets) tends to be true to size. In short: know which range you're buying from before you commit.

I've had my fair share of "what was I thinking?" moments with country brands. I ordered a Jack Murphy Malvern coat in my usual size a few years back, thinking it would be a neat, polished longline rain mac for dog walks — and it arrived looking like I'd borrowed it from someone three sizes bigger. It's built to layer a chunky jumper AND a gilet underneath, which is brilliant if you know that going in. I didn't. Lesson learned, and honestly it prompted me to pay much more attention to how heritage countrywear brands size versus standard high street.

Understanding Jack Murphy's Two Sizing Ranges

Jack Murphy operates across two distinct fit philosophies, and this is the thing that trips most people up:

• Standard Fit — True to size. This covers most shirts, fleeces, lighter mid-layers and casual pieces. Order your usual UK size with confidence.

• Heritage Fit — Runs generously large. This covers the iconic waterproof capes (Malvern, Cotswold), long field coats, wax jackets, and classic waterproof overcoats. These are deliberately cut wide to accommodate multiple layers underneath — that's the whole point of them.

The confusion happens because both ranges share the same size labels (8, 10, 12, 14...) but behave completely differently. Always check the product description before ordering — it will usually state which fit category the piece falls into.

Bear in mind that for Heritage outerwear, the finished garment is cut larger than these measurements suggest — that's by design. Don't assume measuring your bust and matching it to the chart is the whole story.

Specific Garment Sizing Tips

• Waterproof Capes (Malvern, Cotswold) — Size down. These are intentionally oversized to layer over coats and knitwear. If you want a neat, practical look rather than a swamped one, go one full size smaller than usual.

• Long Field Coats & Wax Jackets (Emmet, Erin, Blake) — Slightly large with traditional countrywear proportions. Size down if you prefer a cleaner silhouette, or stay true to size if you plan to layer heavily underneath.

• Mid-Length Jackets (Abbey) — Generous in the body and shoulders. Best to size down if you're between sizes.

• Shirts & Fleeces — True to size, though the fit is relaxed rather than tailored. If you prefer a fitted look, size down one.

• Overtrousers & Legwear — These can run snug, particularly around the hips. Measure your hips carefully before ordering and check the specific product measurements, as these vary more than the outerwear.

• Tweed Blazers (Harriet) — True to size and semi-tailored. These are structured pieces built from Shetland wool, and they fit more like a conventional blazer than the outdoor pieces.

The Layering Logic — Why Jack Murphy Sizes the Way It Does

Jack Murphy is an Irish brand rooted in proper outdoor life — think equestrian activities, country estates, dog walking across muddy fields in February rain. Their Heritage pieces are designed with layering baked in. That means wearing a thick wool jumper, possibly a gilet, and still being able to move freely and stay dry. If you size a Malvern coat to fit snugly over a t-shirt, you'll be cold and frustrated when you actually need it for what it was made for.

That said, I completely understand the frustration when you're looking for that smart longline mac that works equally well in town. The Heritage capes and coats are beautiful — those muted greens, the heritage check linings, the cape detailing — but the fit is not going to flatter in the way a tailored coat does. Size down if aesthetics are your priority. Or choose from Jack Murphy's standard jackets and blazers instead, which genuinely do sit closer to the body.

Smart Alternatives for Similar Styles

If you love that heritage outdoor-meets-polished aesthetic but want more predictable sizing, these brands are worth exploring:

• Barbour — The benchmark for British country outerwear. Their quilted jackets and wax coats are brilliant — true to size and widely available in stores so you can try before you buy.

• Fat Face — Brilliant for relaxed, practical outerwear with a coastal-countryside feel. Consistent sizing and great value for the quality.

• Joules — Their waterproof parkas and wellies-and-dogs aesthetic makes them natural Jack Murphy territory. Generally true to size with a slightly fitted cut.

• Seasalt Cornwall — Genuinely excellent outerwear, particularly for waterproofs and layering pieces. True to size and great for curvier figures.

• White Stuff — Lovely for transitional-season coats and knitwear with that same relaxed country feel. Consistent, true-to-size fit.

• Boden — A good alternative for smart country casual, especially wool coats and blazers. Reliable sizing and a flattering cut for most shapes.

• Crew Clothing — Strong for heritage-inspired casual pieces: rugby shirts, quilted gilets, and smart-casual outerwear that works from countryside to town.

• Gant — If you're after that premium outdoor-heritage aesthetic, Gant does it beautifully in shirts and outerwear. True to size with a slightly refined cut.

For two more under-the-radar picks that genuinely get this space right:

• Rydale — A brilliant equestrian and country lifestyle brand based in Yorkshire. Their coats and jackets are smartly cut, functional, and honestly rival Jack Murphy at a similar price point. Great for women who want practical but polished.

• Hoggs of Fife — A Scottish countryside brand that's been quietly delivering excellent wax jackets and waterproofs for years. Less well-known than Jack Murphy but seriously worth a look — their sizing tends to be more conventional and easier to navigate.
