hanky panky × Casselini: A Tokyo Brand’s First Lingerie Collaboration

For nearly four decades, Casselini has run its collaboration calendar across familiar territory: bag partners, accessory partners, sports-heritage partners, character-licence partners. 2026 is the first year a piece of lingerie carries the Casselini name.

The partner is hanky panky, the New York-based intimate-apparel label founded in 1977 by Gale Epstein and Lida Orzeck, best known for its signature lace styles and its decades-long position in the high-end women’s underwear category. The collaboration — announced via Casselini Inc.’s press release this spring — moves Casselini’s design language out of the bag-and-accessory wardrobe and onto the body itself.

It is the most categorically unusual collab the label has run.

Why this collab matters structurally

Most Casselini collaborations stay inside the bag and accessory category. The exceptions until now have been narrowly defined: T-shirt drops with character-licence partners (WICKED, Care Bears™), capsule footwear with HARUTA, occasional small apparel pieces inside Casselini HOME.

A lingerie collaboration is a structural departure for three reasons:

1. Category — Intimate apparel is sold and merchandised differently from accessories. The product is not displayed openly in the way bags are.
2. Audience entry-point — hanky panky’s customer is recruited through underwear-fashion media and bridal retail, not through accessories editorial.
3. Production — Lingerie supply chains are distinct from accessory supply chains. The collab implies new sourcing relationships for the Casselini side.

Reading the move charitably, the collab signals that Casselini is willing to stretch its design vocabulary into adjacent body-wear categories while keeping its core motif-led philosophy intact. The lingerie register suits Casselini’s flower-and-feminine palette in ways that, say, an outdoor-utility partner wouldn’t.

Reading it commercially, it gives Casselini access to a demographic — the hanky panky customer — that doesn’t necessarily walk into Casselini Harajuku for bags but might be persuaded to investigate the brand via underwear retail.

What hanky panky brings to the table

For overseas readers who haven’t tracked the U.S. intimates market closely, hanky panky is a useful reference point. The label has built its identity around:

• Lace as a finish material, rather than as a decorative accent
• A small core silhouette catalogue (the Original Rise thong being the canonical product) released in a near-infinite rotation of colourways and seasonal capsules
• Independent ownership since 1977 — rare for a fashion label of its scale and tenure
• Long-term retail relationships with U.S. department stores and specialty intimates retailers

That model — core silhouette + extensive colourway rotation + independent operation — aligns unexpectedly well with Casselini’s own approach. Both labels build value through repeat capsules rather than through reinvention. Both rely on partner collaborations to refresh visual codes without diluting the underlying product logic.

The collab capsule applies Casselini’s motif vocabulary to hanky panky’s silhouette catalogue. The reverse — hanky panky’s lace finishes applied to Casselini’s bag forms — would have been easier to execute but would have made for a quieter design moment. The collab leans into the harder direction.

How to read the capsule

For overseas readers wanting to investigate the capsule, the practical reality is that:

• U.S. distribution routes via hanky panky’s own retail and select online channels.
• Japan distribution routes via Casselini’s existing channels — own e-commerce, Casselini Harajuku flagship, select-shop partners.
• The two channels likely do not stock identical assortments. A subset of the capsule is exclusive to each market.

Reading the collab inside Casselini’s broader 2026 cadence

The hanky panky capsule sits alongside Casselini’s other 2026 collaborations — New Era®, WICKED, HARUTA, Care Bears™. The 2026 cadence is unusually dense even by Casselini’s own historical standards.

For an overseas reader new to the brand, start with the collab that maps to your existing wardrobe. The Tokyo accessory market doesn’t recruit overseas customers through editorial discovery — it recruits through the partner brand the reader already follows. hanky panky brings the intimates audience. WICKED brings the film fans. The capsule is the entry point; the brand is what you discover next.
