Italian Linen Meets Hawaiian Rubber and American Denim in WACKO MARIA's Sprawling Three-Way SS26 Collab

Summary

• WACKO MARIA drops a three-way Spring/Summer 2026 collaboration on May 16, linking up simultaneously with Italian textile house SOLBIATI, Honolulu sandal brand HAYN, and American denim institution Wrangler
• The nine-piece lineup spans leopard Hawaiian shirts, ombré check open-collar shirts, Wrangler WRANCHER dress jeans, SOLBIATI double-pleated short trousers, drawstring bags, and two styles of HAYN beach sandals
• The drop continues a dense SS26 collab calendar for the Tokyo label, which has already released with Dickies, Umbro, Dormeuil, McGREGOR, and Terrifier earlier this season

WACKO MARIA‘s Spring/Summer 2026 season has operated less like a single collection and more like a rolling argument for the breadth of the brand’s reference points. The latest evidence arrives May 16, when the Tokyo label drops simultaneously with three collaborators from three different continents: SOLBIATI, the Italian mill whose natural-fiber fabrics have long been a benchmark for warm-weather tailoring; HAYN, the premium sandal brand born in Honolulu and built around high-grade natural rubber; and Wrangler, the American denim brand whose “WRANCHER” dress-up jean sits at an unlikely crossroads of workwear and Western suiting.

To understand why this particular combination makes sense, it helps to understand how WACKO MARIA approaches its collaborations. The brand, co-founded by designer Atsuhiko Mori and director Keiji Ishizuka, has built its identity on what it calls the “Guilty Parties” aesthetic, a sensibility that treats incongruity as a feature rather than a flaw. This season alone, the label has paired with Dickies for utilitarian coveralls, Umbro for football-adjacent tracksuits, and Dormeuil, the British textile house established in 1842, for a capsule of tailored jackets and trousers. Against that backdrop, pulling SOLBIATI, HAYN, and Wrangler into a single drop reads not as a scattershot move but as a deliberate widening of the same creative logic: find partners with deep, specific craft histories, and let the WACKO MARIA attitude hold it together.

The shirting anchors the apparel side of the drop. A Leopard Hawaiian Shirt and a 50’s Open Collar Shirt carry forward the brand’s most recognizable silhouettes, while an Ombré Check Open Collar Shirt introduces a more textural, pattern-driven option that sits closer to the SOLBIATI material story. WACKO MARIA’s Hawaiian shirt has been a through-line across its SS26 collab program, appearing in rayon for the Wes Anderson’s The Phoenician Scheme drop and in Terrifier-branded form earlier in the season. Here it gets a leopard treatment, which in WACKO MARIA’s vocabulary is less novelty print and more house signature.

The SOLBIATI piece is the most considered of the tailoring entries. The Milan-based mill has been producing linen, cotton, and natural-fiber fabrics for well over a century, and its materials carry a weight of provenance that most streetwear brands would struggle to contextualize. WACKO MARIA does not struggle. The Double Pleated Short Trousers in SOLBIATI fabric continue the label’s consistent investment in tailored bottoms this season, and in the mill’s natural-fiber weave they get their most refined execution yet.

The Wrangler piece may be the most culturally loaded. The WRANCHER was Wrangler’s answer to the 1960s American office, a dress-up jean that split the difference between denim casualness and suiting formality. In WACKO MARIA’s hands, that already-hybrid garment gets another layer of reinterpretation. Its provenance, deeply specific to a particular era of mid-century American menswear optimism, fits neatly alongside the brand’s habit of excavating Western references and running them through a Tokyo lens.

HAYN rounds out the drop at the most accessible price points. The Honolulu brand’s Beach Sandals and Leopard Beach Sandals carry WACKO MARIA branding and original motifs into natural rubber construction, pushing the result well past branded flip-flop territory. Two drawstring bags, a standard version and a leopard variant, complete the accessories offering and tie the leopard motif together as a visual thread across the full release.

The WACKO MARIA x Wrangler, HAYN, and SOLBIATI SS26 drop releases May 16 via the WACKO MARIA online store and direct retail locations.
