What is sizing like at Issey Miyake menswear?

Issey Miyake menswear runs most current pieces use a numbered scale from 1 to 6 rather than S to XL, where 1 sits at roughly an XS and 6 at an XXL (6s are rare). The pleated lines — Homme Plissé above all — are the exception, because they're sized by length and height, not by how wide you are. The cloth stretches, the fit is generous, and if you normally take a medium you're usually a 3.

The numbered system, decoded

Newer collections lean on the Japanese numeric scale; older pieces you'll find secondhand tend to use Western letters. As a rough translation:

1 ≈ XS · 2 ≈ S · 3 ≈ M · 4 ≈ L · 5 ≈ XL · 6 ≈ XXL
The structured lines — ISSEY MIYAKE and IM MEN — cut relaxed and are often oversized by design. Don't panic-size-up out of habit.
Fabrication changes the fit between styles, so a 3 in a boxy jacket won't feel like a 3 in a slim knit. It's worth checking the actual garment measurements, not just the label.

Homme Plissé plays by different rules

This is the line most men own first, and it's the one that trips everyone up. Homme Plissé is sized by length, not width — the pleats expand across the chest, waist and hips, so the number you pick is really about how long you want the garment to sit. As a guide, the brand pitches size 1 up to around 171cm in height, 2 for 172–177cm, 3 for 178–183cm and 4 for 184–189cm.

A FAIL I'LL OWN

My first pair of Homme Plissé trousers, I ordered a 3 because I'm "a medium" and didn't read a word about length. I'm 5'9". They pooled around my ankles like a concertina. A 2 would have broken cleanly at the shoe and looked ten times sharper. Lesson learned — with pleats, your height is the number that matters.

How it actually fits, and how to buy it

Pleated pieces mask the body — they drape and skim rather than cling, which is exactly why they flatter almost every build. Choose by height and the drop you want.
Structured pieces run generous. If you're between sizes on a jacket or overshirt, the lower number usually reads more intentional than swimming in the larger one.
Buy the silhouette, not your ego. These clothes are designed to move and float. Sizing down to "fit" defeats the whole point of the cut.

A WIN, FOR BALANCE

I once styled a client who insisted he was "too short for Miyake." We put him in a size 2 Homme Plissé top with straight, cropped trousers and clean white trainers — nothing else. He wore it to a gallery opening and three people asked where the outfit was from. Proportion, not size, is the trick with this label.

Where else to shop a similar look

If you love the architectural, easy-drape feel of Issey Miyake but want options at other price points, these are the labels I steer clients toward. Different brands earn their place for different reasons:

HIGH STREET

COS — the closest high-street cousin. Architectural minimalism, technical and pleated fabrics, and a clean numbered-feeling sensibility for a fraction of the price.
Uniqlo (the U line especially) — Japanese design DNA, superb basics, and collaborations that borrow the same restraint. Unbeatable value for building the foundation of the look.

INDEPENDENT & BOUTIQUE

Universal Works — British, texture-led and relaxed. Brilliant for the loose, considered layering that sits naturally alongside Miyake pieces.
Oliver Spencer — softly tailored with a roomy, unfussy cut, ideal if you want the drape without going full avant-garde.
Folk — playful minimalism and genuinely interesting colour palettes; great for adding personality without shouting.

DESIGNER & LUXURY

Lemaire — fluid, elevated minimalism with that same quiet confidence. If Miyake is your world, this is your next stop.
Auralee — Japanese, with some of the finest fabrics in menswear. Understated to the untrained eye, unmistakable to anyone who knows.
Comme des Garçons SHIRT — the most accessible way into avant-garde Japanese design, and a natural companion to a Homme Plissé wardrobe.
