What Is Sizing Like at Louis Vuitton? A Stylist's Honest Fit Guide

Louis Vuitton clothing runs small and slim. It uses classic French numeric sizing, so most pieces come up at least one size tighter than you'd wear on the British high street — and if you're shopping the tailoring, you'll often want to go up a size from your usual. I've styled enough clients in LV ready-to-wear to tell you that getting the number right is half the battle with this house, so let's get straight into it.

How Louis Vuitton sizing actually works

Louis Vuitton is a French house, and it sizes the French way — numerically, in 34, 36, 38, 40 and upwards rather than the 8, 10, 12 you're used to. As a rough anchor, an LV 38 sits around a UK 10, a 40 around a UK 12, and so on. Tops are cut to your bust measurement and bottoms to your waist, which matters because LV pieces are designed to skim a specific frame rather than drape generously.

The other thing to know: LV is not consistent across the board. Womenswear under Nicolas Ghesquière leans sharp and architectural, and the fit genuinely shifts between categories and seasonal collections. So the "size up or down" answer depends entirely on what you're buying.

Where Louis Vuitton runs small (and where it doesn't)

From a fitting-room point of view, here's how it breaks down:

Tailored jackets and blazers — cut narrow through the shoulders and arms. This is where most people get caught out. Size up if you've got broad shoulders or want to layer underneath.
Trousers and skirts — slim at the waist and hip. The tailored cigarette trousers in particular hug, so don't size down hoping they'll "give".
Structured tops and shirting — fitted, with little ease. Go true to your bust or up a touch.
Knitwear and oversized pieces — far more forgiving. These tend to sit closer to true to size, and the deliberately roomy styles do exactly what they promise.

My honest LV fitting fail (so you don't repeat it)

I'll hold my hands up. Early in my career I sourced a wool LV blazer for a client in what I'd confidently call "her size" — a UK 12, so I grabbed the 40. It would not close across the back, and the sleeves stopped short like she'd outgrown a school blazer. The lesson landed hard: with structured LV tailoring, your high street number is a starting guess, not the answer. We ended up in a 42, and it was flawless. Now I never buy LV tailoring without measurements in front of me — and neither should you.

A stylist's tips for nailing the fit

Measure, don't assume. Take your bust, waist and hip in centimetres and match those to the product page, not the size you wore in something else.
Buy for the broadest point. With jackets that's shoulders; with trousers it's hips. Tailoring a too-tight shoulder is near impossible.
Mind resale value. LV holds its worth, but a piece that doesn't fit you properly is dead money — both in returns and in what you'll recoup if you resell.
Treat each collection on its own merits. A perfect 40 in one season's knit tells you very little about a tailored 40 the next.

Where to shop the Louis Vuitton look — for every budget

LV's appeal is that precise, sculpted French tailoring. You don't need a four-figure budget to get the silhouette, though. Here's where I'd send clients, tier by tier.

On the high street, for that elevated, structured feel:

Reiss — the high street's strongest tailoring; clean blazers and trousers with real polish.
Massimo Dutti — European cut and grown-up fabrics; closest thing to a luxe Continental wardrobe at accessible prices.
Jigsaw — quietly excellent cloth and considered, ageless cuts.
COS — minimalist and architectural, very much in the LV mood for shape.
Whistles — modern, slightly sharp tailoring with a fashion edge.
Me&Em — clever proportions and brilliant for length if you're tall.
Hobbs — structured occasion and workwear that fits like it means it.
Mint Velvet — relaxed-luxe pieces for when you want the polish without the stiffness.

Premium, when you want to invest a step up:

Max Mara — the coats are an institution; few brands do tailored outerwear better.
Theory — clean American tailoring with a sharp, modern line.
By Malene Birger — Scandinavian elevation, beautiful drape and detail.
Totême — quiet luxury done properly; understated pieces that read expensive.

Luxury and designer, in LV's own neighbourhood: Saint Laurent for razor-sharp French tailoring, Chloé for softer Parisian romance, and Celine for pared-back, monochrome cool.

And two left-field independents I love for this look:

The Deck London — an independent British house making suits cut to female proportions, so the shoulders and waist actually land where they should. A genuine answer to LV's narrow tailoring problem.
Róhe — an Amsterdam-based label doing restrained, minimalist quiet-luxury that punches well above its profile. Criminally under-the-radar.
