What Is Sizing Like at Lanvin Menswear?

Lanvin menswear runs broadly true to size, but the tailoring is cut slim and close to the body, so blazers, shirts and trousers can feel a touch smaller than the equivalent from a British high-street brand. If you want that sharp Parisian line, order your usual size. If you like any breathing room across the chest or through the thigh, take the next size up.

The Lanvin cut, explained

Lanvin works to European (EU/IT) sizing, and the tailoring is where most men get caught out. Expect:

Structured shoulders and a suppressed waist. Jackets are designed to nip in, so if you carry any width through the middle, the "true" size can feel snug when buttoned.
Slim through the chest and sleeve. A Lanvin 48 sits closer to the body than a British 38R you might know from the high street.
Trousers cut lean. They're true to EU sizing but read slim if you're used to UK fits — check the thigh and rise, not just the waist.

A quick confession from my own wardrobe: I once ordered a Lanvin blazer online in my "usual" size without checking the measurements, feeling clever. It arrived beautiful and completely unwearable — the shoulders were sharp as a razor and I couldn't lift a pint, let alone my arm. Lesson learned. With this house, you measure first and order second.

Shirts and knitwear

Shirts: tailored and fitted through the body — closer than a classic Jermyn Street cut. If you're between collar sizes, size up rather than down.
Knitwear and outerwear: generally true to size, with the coats and heavier pieces cut in clean, sculptural shapes. These are the safest Lanvin buys to order at your normal size.
Sweatshirts: designed with a more relaxed, casual fit — the one area where Lanvin loosens up.

The trainers (yes, the Curb)

Footwear is the trickiest bit because fit genuinely varies by model, so don't assume one rule covers the lot:

The Curb — the chunky, cut-out cult sneaker — has a padded tongue and can feel slightly narrow. If you've a wider foot or wear thick socks, half a size up is the safer call.
Other lines run large. A few of the cleaner low-tops actually come up generous, and there you'd size down if you're between sizes.

My honest advice: never buy Lanvin trainers blind. I've seen too many men order their "European 43" and end up shuffling around in something that's either pinching or flapping. Match against a shoe you already own and trust the measurement over the label.

What to buy, and how to style it

If you're investing in Lanvin, spend on the pieces that show off the tailoring — a sharp unstructured blazer, a fine-gauge knit, or the trainers if you want the label to do the talking. On trend right now: leaning into that elevated, slightly relaxed Parisian look rather than head-to-toe logo. Pair a slim Lanvin knit with wider, softer trousers to balance the volume, and let one hero piece carry the outfit. Understatement is doing the heavy lifting in menswear at the moment, and Lanvin is perfectly placed for it.

Brands to consider alongside Lanvin

If you love the Lanvin aesthetic but want options at different price points, here's where I'd send you across three tiers.

High street

COS — the closest high-street match for that clean, European, minimalist line. Their tailoring gets you a Lanvin-adjacent shape for a fraction of the outlay.
Reiss — for structured, slim tailoring with a sharp shoulder. Ideal if it's the jacket silhouette you're chasing rather than the logo.

Independent & boutique

Officine Générale — a French label with genuine Parisian refinement, cut a shade more forgiving than Lanvin. Brilliant everyday tailoring.
A.P.C. — for quiet French minimalism, superb denim and understated basics that sit beautifully next to a designer piece.

Designer & luxury

AMI Paris — the natural step across from Lanvin: Parisian, elegant-casual and slightly easier to wear day to day.
Saint Laurent — if you want French tailoring cut even leaner and sharper, this is the sharpest line in the room.
Lemaire — for the softer, more relaxed end of luxury; drapey, considered shapes that balance Lanvin's precision.

Stop guessing your Lanvin size

Here's the frustrating truth: Lanvin, like most luxury houses, rarely gives you full fit detail on retailer sites — no shoulder width, no rise, no insole length — and the men's line varies wildly from the women's.
