What Is Sizing Like at God's True Cashmere?

In short: God's True Cashmere runs true to size but is graded in standard men's sizing and cut deliberately relaxed, so most women will want to size down one — sometimes two — from their usual number to avoid swimming in it. If you normally take a UK 12 in a high street shirt, an XS or S here will usually give you that intended slouchy-luxe drape rather than a tent. This is a unisex, oversized-by-design label, and once you understand that, the fit makes complete sense.

I'll be honest with you — the first time I handled one of these shirts in a fitting room, I nearly put my usual size back on the rail in a panic. The chest measurement looked enormous on paper. Then I tried it, and it was perfect: that easy, fall-off-one-shoulder, throw-it-over-everything fit that you cannot fake with a slim cut. So before you order, let me talk you through exactly how it sits.

How the Fit Actually Works

God's True Cashmere was founded in 2019 (the brand's now-famous origin story involves a dream, Brad Pitt and his friend Sat Hari Khalsa wanting more softness in life — genuinely). Every shirt is 100% cashmere, made in Italy, finished with eleven hand-carved gemstone snaps said to align with the body's chakras. They are gorgeous, and they are a serious investment, so getting the size right first time matters.

Here's what you need to know before buying:

It's graded in men's sizing. The brand and stockists like Farfetch state this plainly. A "Small" is a men's small, which on a woman reads more like a generous medium-to-large.
The cut is unisex and relaxed. Think dropped shoulders, roomy body, long sleeves with pleated cuffs. It's meant to look oversized — that's the whole aesthetic.
It is true to size for what it is. Selfridges lists it as true to size, so the answer isn't "it runs small or large," it's "decide how oversized you actually want it."
The cashmere is midweight and non-stretch. There's no give, so don't size down so far that the shoulders pull or the snaps gape across the bust.
It relaxes slightly with wear. Like most pure cashmere, it softens and gives a fraction over time, so go for a clean fit rather than tight.

My Styling Steer on Choosing Your Size

As a rough guide from someone who's dressed plenty of people in oversized knitwear: if you want that effortless, borrowed-from-him look (and most people buying this brand do), take your usual UK dress size and drop down one men's size. A UK 8–10 often lands beautifully in an XS; a 12–14 in an S; a 16 in an M. If you'd rather it skim closer to the body — say you're petite and don't want fabric pooling at the hem — size down two and treat it as a fitted shirt with a relaxed sleeve.

My one fashion-fail warning: I once talked a client into going a size up "for cosiness" on a similar unisex cashmere piece, and she ended up looking like she'd shrunk inside a duvet. With cashmere this soft and this expensive, you want it to graze your frame, not bury it. The drape does the luxury for you — you don't need extra fabric to feel cocooned.

Where to Shop a Similar Relaxed-Luxe Cashmere Shirt

God's True Cashmere sits firmly at the top of the luxury bracket (shirts run from around £700 to over £2,000), so if you love the slouchy cashmere-shirt look but want options across budgets, here's where I'd send you.

High Street

Uniqlo — the smartest entry point for affordable pure cashmere; their jumpers and overshirts nail that soft, relaxed feel for a fraction of the price.
Marks & Spencer — a reliably good pure cashmere line with consistent sizing and proper quality control for the money.
COS — minimalist, architectural cuts and excellent oversized knitwear; very much the right design language for this look.
Massimo Dutti — elevated, Italian-leaning tailoring and knitwear that punches above its price point.
Mint Velvet — relaxed, off-duty luxe with lovely soft separates designed to layer.
Hush — masters of the easy, throw-on, lived-in aesthetic with plenty of cashmere and cashmere-blend pieces.
The White Company — beautifully made neutral cashmere with a calm, considered feel that suits this slouchy style.

Premium

Brora — Scotland's cashmere specialists and, in my view, the natural step up; exceptional quality and proper heritage knitwear expertise.
Joseph — refined, fashion-forward knitwear with that quiet, grown-up polish.
Toast — artisanal, textural and beautifully relaxed; perfect if you love the considered, less-is-more side of this label.

Luxury / Designer

Max Mara — the gold standard for luxurious coats and knitwear; impeccable Italian cashmere and timeless cut.
Totême — modern, pared-back Scandi luxury with cult-status relaxed knits and shirts.

Two Independent Picks Worth Knowing

Navygrey — a small British cashmere label doing one thing brilliantly: beautiful, responsibly made everyday jumpers in a tight edit of colours.
&Daughter — a family-run, Britain-and-Ireland-made knitwear brand with gorgeous natural-fibre pieces and real craft credentials.
