What Is Sizing Like at Sasuphi?

Sasuphi runs broadly true to size, but it's labelled in Italian (IT) measurements and cut with a quiet architectural ease — so most women take the IT size that matches their usual fit rather than instinctively sizing up or down. That's the headline, and if you're hovering over a basket at checkout, that's really all you need. But Sasuphi is one of those labels where understanding why it fits the way it does will save you a return, so let me talk you through it properly.

I've been styling clients into Milanese tailoring for years, and Sasuphi has fast become one of my favourite quiet-luxury recommendations since the brand launched in 2021. Founded by Sara Ferrero and Susanna Cucco — two women with serious fashion-house pedigree between them — it's built on beautiful Italian fabrics, clean lines and a "buy it, keep it forever" philosophy. The fit follows that same logic: precise, but never punishing.

How Sasuphi sizing actually works

Here's the bit that trips people up. Sasuphi uses the Italian numbering system, which looks alarming if you're used to UK or US labels. An IT number sits a fair way above the UK size you know — so when you see a "42" on the tag, don't panic and assume you've gone up four sizes overnight. It's simply how Italy counts.

Read the IT label, not the number's "feel". The smaller IT figures map to the smaller UK sizes, and they climb in steps of two, just like ours do.
Take your normal size. Sasuphi doesn't play games with vanity sizing — what you'd usually wear is a safe starting point.
Between sizes? Size up. The fabrics are natural and substantial (think proper silk and cashmere), so a touch of room lets them hang the way the designers intended.

The fit by garment type

Sasuphi's silhouette is "soft architecture" — sharp on the eye, relaxed on the body. It varies a little depending on what you're buying, so here's my fitting-room shorthand:

Shirts & crêpe-de-chine blouses: generous and fluid through the body with a slightly dropped shoulder. Don't size down hoping for a neater fit — you'll lose the lovely drape that makes them special.
Cashmere & knitwear: true to size with a relaxed, lived-in ease. The cashmere is finespun and soft, so it skims rather than clings.
Tailoring & trousers: clean and considered, cut for movement. The waistbands sit comfortably rather than nipping — flattering if you carry a little through the middle.
Satin skirts: these sit closer to the body, so go with your true measurement and trust it.

My honest styling advice (and a confession)

A quick fashion fail of mine: years ago I bought my first piece of Italian tailoring, saw a number in the forties, assumed it was enormous and reached for the smaller one. It arrived, I couldn't do up the buttons, and I learned my lesson the hard way over the kitchen bin. Italian sizing is not your enemy — it just speaks a different language.

So with Sasuphi: ignore the number, trust the measurement. The pieces are designed to be re-worn and re-styled season after season, which means the fit needs to be comfortable for real life, not just the rail. If you love a sharper line, a good tailor can take a centimetre off a sleeve or a hem — but I'd never advise sizing down to fake it. Buy the size your body actually is and let the cut do the work. That's the whole point of the brand.

Love the look? Where else to shop the Sasuphi aesthetic

If you adore that pared-back, fabric-led Milanese feel but want options across budgets, these are the brands I steer clients towards.

High street

COS — the closest high-street cousin to Sasuphi, all architectural lines and matte, weighty fabrics.
Massimo Dutti — Italian-influenced tailoring with a grown-up fabric story for the price.
Jigsaw — beautifully cut British staples and knitwear that punch above their tier.
Whistles — modern, clean separates and tailoring with a minimalist edge.
Reiss — polished tailoring and occasionwear when you want a crisper finish.
Me&Em — clever cuts designed by women who understand real bodies; brilliant for elevated workwear.
Mint Velvet — relaxed-luxe in soft, tactile fabrics for the off-duty Sasuphi mood.
Hush — easy, understated staples that layer effortlessly under sharper pieces.

Premium

Cefinn — sleek, considered tailoring built for the working week; very much the Sasuphi spirit.
Baukjen — sustainable, beautifully draped pieces with a quiet, modern confidence.
Sézane — Parisian elegance and lovely natural fabrics with that effortless French ease.

Luxury & designer

Max Mara — the gold standard for Italian coats and camel tailoring (and a brand Sasuphi's co-founder once art-directed).
Joseph — minimalist wardrobe architecture and exceptional knitwear; pure clean-lined luxury.
Totême — Scandinavian restraint and impeccable cut for the modern minimalist.

Two left-field independents worth knowing

ESSE Studios — an Australian label making genuinely architectural, sculptural minimalism in lovely fabrics. If Sasuphi speaks to you, this will too.
La Collection — a small Parisian independent specialising in fluid silks and elevated essentials, quietly brilliant and still under the radar.
