What Is Sizing Like at Haikure?

Haikure runs broadly true to size in the waist, but the whole label is cut for volume — so the honest rule is that its relaxed and oversized denim sits roomy (size down if you’re between two sizes), its structured tailoring lands true, and its more fitted pieces can run a touch small. Get the silhouette right rather than chasing a single number on the label, and Haikure fits beautifully.

I’ll be upfront: the first pair of Haikure jeans I ordered, I bought my usual size on autopilot and ended up swimming in them. They were one of their lovely baggy boyfriend cuts, and on my frame the extra fabric pooled at the ankle and dragged the whole proportion down. I sized down one, and suddenly the same jeans looked editorial instead of borrowed-from-a-taller-friend. That’s Haikure in a nutshell — gorgeous denim that rewards you for reading the cut, not the size tab.

First, a Quick Word on the Brand

Haikure is an Italian denim house founded near Perugia in 2011, and it sits firmly in the premium, sustainable, minimalist corner of the market. Think organic cotton, traceable production, clean washes — sun-faded light blues, inky blacks, mineral greys — and quietly luxurious cuts with no loud branding. The name fuses the Japanese haiku with the brand mantra “nature, pure, future,” which tells you everything about the pared-back aesthetic.

Because it’s Italian, the sizing is built on IT measurements that don’t map neatly onto a UK chart. That’s the single biggest reason UK shoppers get caught out — so always cross-check your waist and hip measurements in centimetres or inches against the specific garment rather than assuming your usual high street size carries over.

Haikure Sizing by Garment

Haikure’s fit really does change depending on what you’re buying. Here’s how I’d guide you piece by piece.

Relaxed & Oversized Jeans

Run roomy by design. The balloon, baggy and boyfriend cuts (the Bibi and Bethany families, for example) carry deliberate volume through the leg and seat.
Size down if you’re between two sizes — you’ll keep the relaxed look without drowning in fabric.
The waist itself tends to sit true, so if the waistband fits and only the leg feels excessive, that’s the intended silhouette, not a sizing error.

Straight & Structured Jeans

Closer to true to size than the baggy styles, with a more tailored line from hip to hem.
If you like a sharp, clean leg, take your normal size and check the rise — Haikure favours a high-rise waist that lengthens the leg.

Trousers & Tailoring

Generally true to size, but the fluid, relaxed-waistband styles are forgiving and can take a fitted look if you size down.
Always check the hip measurement — Italian tailoring is often cut leaner through the hip than UK equivalents.

Jackets & Outerwear

Oversized by default. Most of the denim jackets and overshirts are designed to layer with room to spare.
Size down for a tailored fit if you want it sitting close rather than slouchy.

Fitted Pieces & Dresses

The cropped jackets and body-skimming denim dresses are the exception — they can run true to size or even slightly small.
If you’re curvier through the bust or hip, consider sizing up here rather than down.

My other small confession: I once nearly returned a Haikure denim jacket convinced it was mislabelled, because it was so much bigger than my usual. It wasn’t a fault — it was the cut. Sized down one, belted it over a slip dress, and it became one of the most-worn things in my wardrobe that summer. The lesson stuck: with this brand, trust the silhouette description over your instinct.

If Haikure Isn’t Quite Right — Where Else to Shop

If the price point, the wait, or the sizing gamble puts you off, there’s a whole world of clean, well-made, sustainably-minded denim that gives you the same quiet, considered look. Here’s where I’d send you.

On the High Street

Weekday — the Swedish label is probably the closest high street match: organic-cotton denim, relaxed and straight cuts, and that same understated, slightly androgynous feel.
Monki — playful but genuinely good on volume denim, with generous baggy and wide-leg fits at an accessible price.
& Other Stories — strong on minimalist, well-cut jeans and elevated basics with a Scandi sensibility.
Mango — reliably chic denim with plenty of straight and high-rise options that nail the editorial look for less.
Massimo Dutti — for the structured-tailoring side of Haikure; beautifully cut trousers and clean denim with grown-up polish.
Uniqlo — unbeatable for honest, true-to-size denim basics when you want the clean look without any fit drama.

Independent Brands Worth Backing

MUD Jeans — the Dutch circular-denim pioneer leases and recycles its jeans, with relaxed and straight cuts that sit squarely in Haikure territory on ethics and aesthetic.
E.L.V. Denim — a London independent making one-of-a-kind jeans from upcycled vintage denim; properly sustainable, properly directional, and a genuine talking point.

Premium Pick

Closed — the German label is the natural step-across: relaxed, beautifully constructed denim with the same sustainable credentials and the same grown-up minimalism.

Luxury Pick

Toteme — if you love Haikure’s pared-back lines and want to invest, Toteme’s clean, architectural denim is the most natural upgrade.

The Bottom Line

Haikure is some of the loveliest sustainable denim out there — but it rewards a bit of homework. Read the cut, check your measurements in centimetres, size down on the baggy and oversized styles, and stay true (or even size up) on the fitted pieces. Get that right and you’ll understand exactly why it’s become such a quiet cult favourite.
