What is Sizing Like at Miu Miu?

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

Miu Miu runs small — typically one to two sizes smaller than standard UK high street sizing — and if you've ever arrived home from a boutique buzzing with excitement only to discover you can't quite get a skirt over your hips, you'll know exactly the kind of heartbreak I'm talking about. I've been there. Let me save you the trouble.

Miu Miu, Miuccia Prada's beloved younger, quirkier sister brand, follows Italian sizing conventions. That means a Miu Miu 38 is broadly equivalent to a UK 8 to 10, but the cut — especially on tailoring, knitwear and their signature mini skirts — often runs quite fitted. The brand was built on a very specific body silhouette: think slender proportions, narrow shoulders, and a slightly cropped waist. Beautiful, yes. Accommodating of a real-life body in all its glorious variety? That takes a little navigation.

Understanding Miu Miu's Italian Sizing

Like most Italian luxury houses, Miu Miu uses the European sizing system. The numbers can feel alien if you're used to UK sizing, and the leap between sizes can be uneven — so please, don't just grab your usual number and hope for the best. The first thing to know: always size up at least one size, and for anything fitted or structured, potentially two.

I once tried on a Miu Miu ribbed cardigan in what I thought was my size and it looked like I was attempting to squeeze into a child's school jumper. Lesson learnt. Now I always go a full size up and, honestly, the fit is perfect.

How Sizing Works Across Different Miu Miu Categories

Miu Miu is not a one-size-fits-all situation — and I mean that quite literally. Each category behaves a little differently, so here's my honest breakdown:

Mini Skirts & Tailored Skirts: These are notoriously fitted, especially around the hips. If you're between sizes, absolutely go up. The brand's iconic pleated and pencil cuts leave very little wiggle room — and I mean that literally. Size up and get it tailored if needed; it's worth every penny.
Dresses: Depends heavily on the silhouette. Shift dresses and slip styles can be more forgiving, but anything ruched or structured will hug tightly. If you have a fuller bust, go up a size and consider a good seamstress for the waist.
Knitwear & Cardigans: Miu Miu's knits run slim. The ribbed styles in particular are cut very close. I'd recommend sizing up one — two if you prefer a relaxed, layered look (which, frankly, is very on-brand for the aesthetic).
Coats & Outerwear: These tend to have slightly more ease than the ready-to-wear. That said, they're still cut with a narrow shoulder — if you carry width in your shoulders, try before you buy, or look for styles with raglan or dropped-shoulder cuts.
Footwear: Miu Miu shoes generally run true to size, though styles with a narrow toe box (which is most of them, if we're honest) can feel snug. Half-size up if you're between sizes or have a wider foot.
Bags & Accessories: No sizing issues here — just pure joy. The Miu Miu Wander bag and Arcadie are absolute investment pieces and I am not sorry about it.

The Miu Miu Aesthetic — And Why Fit Matters So Much

Part of what makes Miu Miu so irresistible is that the brand has a very clear, intentional point of view. It's playful, irreverent, and unashamedly feminine — but with this brilliant undercurrent of intellectual quirkiness. Think ballet flats and micro-bags paired with ankle socks and a perfectly-cropped cardigan. It's the kind of brand that makes you feel like you're in on a very chic inside joke.

But because the brand builds its visual identity around a very close, precise fit, getting your size right is everything. A too-tight Miu Miu mini skirt doesn't give that effortless Parisian effect — it just looks uncomfortable. A too-large size, on the other hand, loses all the elegant structure that makes the clothes so special. The sweet spot is a size that fits cleanly through the waist and hip, with just enough room to move gracefully.

My advice? If you're shopping in a boutique, take two sizes into the fitting room. If you're shopping online, measure your waist and hips carefully and compare them to the garment measurements on the product page — not just the size guide.

How to Get the Miu Miu Look Without the Miu Miu Price Tag

Let's be real — Miu Miu is a significant investment, and not every wardrobe (or bank account) has room for it. But the good news is that the playful, feminine, slightly quirky aesthetic it champions has never been more widely available. Here's where I'd look:

HIGH STREET PICKS

Anthropologie — Genuinely one of the best high street options for the Miu Miu-adjacent aesthetic. Feminine prints, quirky detailing, and a styling sensibility that doesn't take itself too seriously. Their knitwear and dresses are particularly strong.
Mango — Mango has had a remarkable glow-up over the past few seasons. Their tailored mini skirts and fitted blazers capture that European sensibility well, and the quality has genuinely improved.
Cos — For the more pared-back, architectural side of the Miu Miu DNA. Clean silhouettes, interesting fabrics, and pieces that feel considered rather than trend-chasing.
Whistles — Lovely feminine tailoring and a polish that belies the price point. Their knitwear is particularly worth exploring if you love Miu Miu's cosy-luxe cardigans.
Ted Baker — If it's the feminine-with-flair direction you're after, Ted Baker delivers consistently. Especially good for occasion pieces and dresses with that delicate, detailed touch.
Phase Eight — Brilliant for dresses with real elegance, and they size far more generously than Miu Miu, which makes the whole experience considerably less stressful.
Hobbs — Think quiet luxury at a fraction of the price. Their tailored pieces are excellent, and if you love Miu Miu's more grown-up, structured side, Hobbs consistently delivers.
Me&Em — A brand that's earned its loyal following for good reason. Well-cut, intelligent basics with a grown-up edge — and critically, the sizing is honest and consistent.

PREMIUM PICKS

Claudie Pierlot — Honestly, this is the closest the premium market gets to capturing Miu Miu's Parisian-feminine energy. Charming prints, romantic silhouettes, and a consistent quality that makes it a genuinely great investment.
Reiss — For the sleeker, more architectural side of the look. Excellent tailoring, reliable sizing, and pieces that work hard in a wardrobe.

INDEPENDENT & LEFT-FIELD PICKS

Cecilie Bahnsen — A Copenhagen-based designer who creates the most exquisite, voluminous, romantic pieces — think sculptural dresses with a dreamlike femininity that feels genuinely Miu Miu-adjacent. Not cheap, but a considered alternative that's far more under-the-radar.
Réalisation Par — The Australian brand beloved by fashion insiders for its beautifully crafted silk slip dresses and feminine prints. It has exactly the playful, slightly louche quality of Miu Miu's slip dresses but at a more accessible price point. Genuinely brilliant.
