9 Objects That Explain Aiayu's Spring 2027

The Oilskin Bomber Jacket

Aiayu's slouchy oilskin bomber is the collection's sole new silhouette, but the shape is deliberately familiar—creative director Maria Høgh Heilmann calls it something you always go back to, on par with a classic denim jacket. Oilskin is a waxed cotton that repels water through its saturated fiber surface rather than through a synthetic membrane or chemical DWR coating; the material has been used in maritime workwear for over a century because it blocks wind and rain while remaining breathable enough for active use. The bomber arrives in the first of three drops scheduled from January through March 2027, a staggered cadence that spaces the introduction of new pieces alongside restocks of established ones. Aiayu produces the jacket in undyed earthy neutrals—shades that sidestep synthetic dye processing and keep it compatible with wardrobes built around the brand's existing palette. The January timing places it in the collection's lightest layering tranche, positioned to be worn open over cotton-silk pieces in mild weather and zipped over Bolivian llama wool knits when temperatures drop. A reader reaching for it gets a garment that does the work of a technical shell without looking like one, built from a fiber-and-finish combination that improves with wear rather than degrading.

Bolivian Llama Wool Knitwear

Bolivian llama wool gave Aiayu its raison d'être more than 20 years ago, and the fiber remains the collection's structural backbone. Llama wool is harvested from animals raised on the Bolivian altiplano, where extreme temperature swings produce a fleece with natural insulating properties; the result is knitwear with a warmth-to-weight ratio that lets a single layer replace two of conventional wool. Aiayu has built two decades of technique around working with this fiber—spinning, knitting, and finishing methods calibrated specifically to llama's characteristics. For Spring 2027, the wool appears entirely undyed, showcasing the fiber's natural tonal range from pale fawn through warm tawny to deep umber, a palette that shifts depending on which part of the animal the fleece comes from. The brand's 'Notes on Materials' event series invites guests to handle the fabric directly at a dedicated fabric-encounter station, because—as Høgh Heilmann argues—seconds on a runway cannot convey what touch reveals about llama wool's density, loft, and soft hand. The pieces are transeasonal by construction: light enough to wear as a mid-layer under the oilskin bomber in January, warm enough to stand alone as outerwear by March, and durable enough to remain in rotation for years without pilling or thinning.

The Cotton-Silk Jacquard Dress

A wispy cotton-silk jacquard bearing an organic leaf print brings light femininity to an otherwise androgynous black dress. The cotton in this fabric is sourced from India; silk is blended at the fiber stage, meaning the two materials are spun together before weaving rather than layered afterward, which produces a cloth with the breathability and moisture absorption of cotton married to the drape and surface sheen of silk. The jacquard weave raises and depresses individual threads to create the leaf motif through structural texture rather than printed decoration, so the pattern reads as shadow and relief up close and as a soft tonal variation from across a room. Aiayu stages the dress's reveal not at a show but at a 'Notes on Materials' gathering where guests handle the fabric themselves, because—as Høgh Heilmann puts it—seconds on a runway cannot convey what touch reveals about a textile's weight, hand, and movement. The dress arrives in the first of three drops, placing it in the lightest layering tranche, where it can be worn over a cotton poplin trench in transitional weather or beneath a Bolivian llama wool cardigan as temperatures cool. The organic leaf print sits within Aiayu's undyed, earthy-neutral palette—black on black—so it reads as detail rather than statement, and remains compatible with pieces from previous seasons and future drops.

The Cotton Poplin Trench

A densely woven cotton poplin trench delivers water resistance through the tightness of its weave alone—no harsh coatings, no synthetic finishes. Poplin is a plain-weave fabric with a higher thread count per square inch than most cottons, producing a surface so closely packed that water beads on contact rather than penetrating; the mechanism is the same one that makes tightly woven sailcloth shed rain, and it works because cotton fibers swell when wet, closing the gaps between threads even further. The jacket's check print is a hallmark of the material itself—a byproduct of the poplin's construction, where alternating colored and uncolored yarns create pattern through weave structure rather than applied pigment. That same check pattern is mirrored in a flowing seersucker pant, creating a material dialogue between structured outerwear and relaxed legwear. The trench arrives in one of three drops scheduled across the first quarter of 2027, positioned to serve as a transitional outer layer when paired with lighter cotton-silk pieces beneath, or as a mid-layer under the oilskin bomber as the season progresses. Aiayu sources the cotton from India and processes it without chemical finishes, keeping the garment within the brand's undyed, earthy-neutral palette—natural cream and warm tan—so it remains compatible with wardrobes built around the label's existing knitwear and linens.

The Seersucker Pant

A flowing seersucker pant picks up the check pattern that runs through the cotton poplin trench, translating it into a fabric whose puckered surface lifts cloth away from the skin. Seersucker achieves its texture through alternating slack and tension threads on the loom, creating raised ridges and recessed channels that produce natural airflow without openings or perforations; the fabric breathes because air circulates through the channels, making it genuinely transeasonal rather than merely marketed as such. The check print emerges from the weave structure—the same material-driven detail that marks the trench—so the pattern is inherent to the cloth, not printed on. The pant arrives in one of three drops scheduled across the first quarter of 2027; in January it layers beneath a cotton-silk dress or an androgynous black top, and by March it stands alone with a simple cotton tee as temperatures rise. A reader reaching for the pant gets a garment that does the work of linen—breathable, textured, relaxed—without linen's tendency to wrinkle, because seersucker's puckered surface is designed to look rumpled from the outset. Paired with the cotton poplin trench, the two pieces create a coordinated outfit where check pattern and texture carry the visual weight without relying on color or cut.

'Notes on Materials' Event Series

Rather than staging a show or presentation, Aiayu mounted a three-part series of intimate gatherings under the umbrella 'Notes on Materials,' each designed to make the collection's sourcing tangible. The first event was a styling and fitting session where guests tried garments on, moved in them, and saw how cotton-silk layered over cotton poplin, how seersucker sat against oilskin, how Bolivian llama wool knits behaved when worn rather than hung. The second was a library of trims and found objects—buttons, closures, selvedge edges, fiber samples—laid out for guests to handle, a tactile reference library that made visible the decisions embedded in each finished piece. The third was a direct fabric encounter spanning cotton sourced from India, yak and cashmere from Mongolia and Nepal, flax-linen from Europe, and Bolivian llama wool—the five fiber families that form the collection's material base. The scale of the sourcing—four continents, five distinct fiber traditions—demanded a format where each origin story could land with the weight a conventional runway, where garments pass in seconds, could never support. Høgh Heilmann's argument is simple: materials are something you need to touch and wear yourself, because then you feel the difference. The gatherings run alongside the collection's three-drop schedule, timed so that each event introduces the fibers and silhouettes arriving in the next release.

The Three-Drop Schedule

Spring 2027 arrives in three parts, rolling out from January through March rather than landing as a single seasonal shipment. The first drop in January carries the collection's lightest layering pieces: cotton-silk jacquard dresses, seersucker pants, and the new oilskin bomber, all positioned to be worn over or under each other in transitional weather. The second and third drops introduce heavier Bolivian llama wool knits and cotton poplin trench coats as temperatures shift, spacing demand across the quarter and keeping the assortment fresh rather than overwhelming a single moment. The staggered cadence also lets Aiayu restocks of proven pieces—silhouettes customers already reach for repeatedly—alongside new introductions, so the bomber arrives next to a denim jacket's equivalent in llama wool rather than displacing it. Høgh Heilmann builds the schedule around her stated disbelief in seasons: clothes are meant to be worn year-round for years, so there is no reason to flood a single moment with product that could serve customers across three months of changing conditions. The format gives a reader time to see how pieces interact across drops—a January seersucker pant paired with a March llama wool cardigan, a February cotton poplin trench over a January cotton-silk dress—before committing to a purchase.

The Color Palette

Much of the collection is undyed, relying on the natural tones of llama wool, cotton, and linen—shades that range from pale fawn through warm tawny to deep umber, determined by the fiber source and the part of the animal or plant from which it comes. Small injections of sun-washed blossom pinks, burnt yellows, and muscovado browns appear in select pieces, alluding to the turning of the seasons without committing to a trend-driven palette that would date the garments by next year. The approach keeps individual pieces compatible across years and with existing wardrobes: an undyed llama wool cardigan bought in January pairs with a muscovado-brown cotton poplin trench from a previous season, and a blossom-pink cotton-silk top from March sits against an undyed seersucker pant without clashing. Undyed neutrals also sidestep the chemical processing that synthetic dyes require—no dye baths, no fixatives, no wastewater from color application—keeping the garments within the brand's material philosophy from fiber sourcing through finishing. The palette arrives across all three drops, with the lightest tones (fawn, cream, blush) front-loaded in January and the deeper earth tones (burnt yellow, muscovado brown) appearing in later releases as the season shifts.

Transeasonal Layering as Design Principle

Høgh Heilmann builds each season on silhouettes, forms, and materials the brand already knows work, mixing them in new combinations rather than chasing novelty. The Spring 2027 lineup layers cotton-silk over cotton poplin, seersucker against oilskin, and Bolivian llama wool beneath lighter cotton pieces—pairings chosen because each fabric's weight, breathability, and texture complement the others without redundancy. A cotton-silk jacquard dress over a cotton poplin trench in January becomes a different garment than the same dress worn alone in March, and the oilskin bomber zipped over a llama wool knit replaces the need for a separate winter coat. Aiayu sources cotton from India, yak and cashmere from Mongolia and Nepal, flax-linen from Europe, and Bolivian llama wool—five fiber families drawn from four continents, each with distinct thermal, moisture, and structural properties that determine how it layers. The result is a wardrobe where a January purchase and a March purchase work together and with everything the customer already owns, because the pieces are designed around material compatibility rather than seasonal color stories or trend cycles. A reader assembling a transeasonal wardrobe from this collection can mix across drops without planning: the seersucker pant's check print echoes the cotton poplin trench's, the bomber's oilskin sits over any knit, and the undyed palette ensures every piece tones with every other.
