What Is Sizing Like at Pleats Please Issey Miyake?

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

Pleats Please Issey Miyake uses its own sizing system — numbered 1 through 5 — which bears no direct relation to standard UK, US, or EU sizes. The good news? The permanently pleated fabric stretches generously, meaning each size accommodates a wider range of bodies than conventional sizing ever could. Once you understand the system, it's actually one of the more liberating brands to shop. Here's exactly how it works.

I have a very distinct memory of the first time I handled a Pleats Please garment. A colleague brought one in — a long, column-like pleated dress in the most extraordinary deep plum — and I picked it up expecting it to weigh almost nothing, because the fabric looked so lightweight and almost paper-like. And it did weigh almost nothing. Then I noticed the size label: just a single digit. The number 3. No S, M, L. No 10, 12, 14. Just 3. "What does that mean?" I asked. "It means it fits me," she said, "and it'll probably fit you too." She was right. That's Pleats Please in a nutshell.

This is a brand that operates by its own rules — and understanding those rules makes the whole shopping experience click into place.

The Pleats Please Sizing System Explained

Issey Miyake's Pleats Please line, launched in 1993, was built around a completely different philosophy to conventional fashion. The signature permanently-pleated polyester fabric — each garment pleated after construction, not before — creates a material that stretches, moves, and drapes in ways that static fabric simply cannot. This has one very significant practical consequence: each garment fits a far wider range of body sizes than the number on the label implies.

The sizing runs from 1 to 5, and here's the rough breakdown:

Size 1 — Very petite to small. Best for UK 6–8, very slim UK 10. Slim through the torso when worn.
Size 2 — The most popular entry size. Best for UK 8–10, sometimes a relaxed UK 12. The sweet spot for most smaller-framed women.
Size 3 — The brand's "middle" size and the most versatile. Works beautifully on UK 10–14. The drape really comes into its own here — enough fabric to flow, not so much it overwhelms.
Size 4 — For UK 14–18. Still beautifully proportioned — the pleating scales well. Don't be tempted to stay at a 3 if you're a UK 16; the 4 will hang better and move more freely.
Size 5 — For UK 18–22. The full silhouette of these garments at size 5 can be genuinely spectacular — the pleating creates volume that feels intentional and architectural, not oversized.

Ella's Key Rule: When in doubt, go up a size — not down. The pleated fabric will accommodate, and a slightly larger size drapes more elegantly. A size that's too small will pucker at the pleats and pull across the body, defeating the entire point of the construction. The brand is specifically designed to flow, not cling.

This is a guide — individual garment measurements vary, so always check the specific product listing where measurements are given in centimetres:

One important note: Pleats Please garments are measured flat and un-stretched. The actual wearing ease is considerably more generous than these numbers suggest, thanks to the stretch in the pleating. If your measurements fall right on the boundary between two sizes, always go up.

Does the Fit Vary by Garment Type?

Yes — and this is worth knowing before you order, particularly if you're buying online.

Dresses and skirts: These are where Pleats Please truly shines. The pleated column silhouette is forgiving, elegant, and genuinely flattering on an enormous range of body shapes. The pleat creates vertical lines that elongate. True to the size guide — or up one if between sizes.
Trousers: A slightly more technical fit because of the waistband. Most Pleats Please trousers have an elasticated waist, which helps, but the leg width and length are fixed. Petite wearers sometimes find the trouser length overwhelming — the pieces aren't designed with height adjustments in mind. If you're under 5'4", this is worth factoring in.
Tops and blouses: These can be deliberately oversized in silhouette — that's often the intention, not a sizing issue. Check the individual garment description for whether the style is meant to be fitted or relaxed. When in doubt: size up for the flowing look; stay at your size for something more structured.
Jackets and outerwear: The pleated construction on outerwear means these sit away from the body more than you might expect. If you're used to fitted tailoring, this can feel like a big shift. Embrace it — the volume is the point. Size as per the guide, and try before you buy if you can.
Knits (the non-pleated pieces): Pleats Please does occasionally produce non-pleated knit pieces. These follow more conventional Japanese sizing — which runs small by UK standards. A Japanese M is broadly a UK 10–12. Check measurements carefully.

The Fabric — Why It Changes Everything

I want to spend a moment on the fabric, because it's genuinely unlike anything else in fashion and it's central to understanding the brand. The signature polyester is heat-treated and permanently pleated, which means it doesn't crease, it doesn't need ironing, it can be scrunched into a ball in a suitcase and come out looking perfect. I have clients who travel extensively who practically live in Pleats Please for this reason alone.

It also ages exceptionally well. I have pieces that are over a decade old that look exactly as they did when they were new — the pleating holds, the colour stays true, and the fabric doesn't pill or bobble. For the price point (and Pleats Please is not cheap — expect to pay £200–£600+ for most pieces), this longevity genuinely justifies the investment. These are not fast fashion purchases. They are wardrobe staples that outlast almost everything else.

My Honest Styling Advice for Pleats Please

The brand has a very specific aesthetic vocabulary — Japanese minimalism with a sculptural, slightly avant-garde edge — and it's worth knowing how to wear it well rather than just hoping for the best.

Let one piece lead. A Pleats Please dress or trouser doesn't need much company. Keep everything else simple — clean lines, neutral colours, minimal accessories. Let the pleating do the talking.
It works brilliantly with flat shoes. Loafers, sandals, clean trainers. The relaxed but considered silhouette pairs well with unfussy footwear. Very high heels can tip it into costume territory.
It's one of the best brands for women who hate being uncomfortable. The stretch, the breathability, the lack of structure — you will be genuinely comfortable all day, which is a statement few investment pieces can make.
The block colours are the most versatile starting point. Pleats Please does extraordinary prints, but if you're new to the brand, start with a single solid colour — the black pleated trousers or a stone column dress — and build from there. The prints are a commitment.

If Pleats Please Isn't Right for You — Brilliant Alternatives

The Pleats Please universe is quite specific — but if you love the idea of architectural, relaxed, Japanese-influenced dressing at various price points, these are my honest picks:

🛍 HIGH STREET & ACCESSIBLE

COS — The most natural high street comparison for the Pleats Please aesthetic. COS shares the same Scandinavian-meets-Japanese minimalism, clean architectural shapes, and interest in fabric. Sizing is standard EU/UK, slightly relaxed fit throughout. A brilliant entry point for this whole design vocabulary.
Massimo Dutti — For the elevated, quiet luxury end. Their pleated trouser and wide-leg separates programmes are excellent, and the fabrication quality is genuinely impressive for the price. True to EU sizing.
Whistles — A consistently underrated brand for this kind of pared-back, considered dressing. Their pleated and wide-leg pieces are beautifully cut and very wearable. True to UK sizing.
Jigsaw — Brilliant for the relaxed, slightly intellectual, beautifully made end of British fashion. Their pleat-front trousers and easy dresses are excellent. True to size, slightly generous.
Anthropologie — For a more relaxed, bohemian take on the pleated/draped silhouette. Not as architectural as Pleats Please, but genuinely beautiful fabrication and a very individual approach to design. True to size.
Hush — Seriously good for relaxed, well-made everyday pieces in the same easy, unconstructed spirit. Not avant-garde, but the quality-to-price ratio is excellent and the fit is wonderfully accommodating. True to UK size.
Part Two — A Scandinavian brand with excellent UK distribution that does the minimalist, architectural silhouette very well. Their pleat-front trousers and structured wide-leg styles are superb. True to EU/UK size.

✨ PREMIUM STEP-UP

Me&Em — For the polished, contemporary British approach to easy dressing. Their wide-leg trousers and fluid dresses are extremely well made, fit a wide range of body types, and the quality has improved dramatically in recent seasons. True to UK size.
Claudie Pierlot — The French take on this — less architectural, more feminine, but with the same appreciation for interesting fabric and considered silhouette. Worth exploring if you want a softer version of the aesthetic. Check their FR sizing against your UK size.

💎 INVESTMENT & DESIGNER

Acne Studios — Swedish design with a similar intellectual, slightly difficult-in-the-best-way approach to proportion and silhouette. The fit philosophy is comparable — oversized where it should be, precise where it matters. EU sizing, runs slim.
Max Mara — For the ultimate investment in Italian craftsmanship with an easy, architectural silhouette. Their wide-leg trousers and long line coats share that same sense of effortless authority. True to EU sizing.

🌿 INDEPENDENT PICKS YOU NEED TO KNOW

Ahluwalia — A British-Nigerian designer whose work sits in a fascinating space between sculpture, craft, and wearability. If you're drawn to Pleats Please because of its refusal to look like everything else, Ahluwalia is the next logical step. Pieces are made in limited runs — the opposite of fast fashion — and the craftsmanship is extraordinary. Sizing is made-to-measure or standard S/M/L with generous ease.
Toga Archives — A Japanese brand that is as close to the Pleats Please spirit as you'll find outside of Issey Miyake itself. Sculptural, avant-garde, deeply considered in its approach to fabric and construction. Available at select independent UK boutiques and online at SSENSE. Japanese sizing — always check measurements.
