Wacoal Corp. (Headquarters: Kyoto, Kyoto Prefecture; President and CEO: Keisuke Kawanishi) is launching the second installment of its triple collaboration, "WACOAL Swim Wear x SPORTIFF by Risako Miura." This collaboration involves Wacoal's "Wacoal Swim Wear," the apparel brand "SPORTIFF" operated by Sportiff Inc.

The new swimwear collection, which combines glamour and comfort, will be available from Tuesday, April 14, 2026, at authorized retailers nationwide and on e-commerce sites including the Wacoal Web Store.
This is the second collaboration following the Fall/Winter 2025 season, bringing together "Wacoal Swim Wear," which has been proposing "swimwear for adult women that they want to show off" by leveraging its innerwear expertise; "SPORTIFF," an adult casual brand from Chigasaki; and Ms. Risako Miura, a fashion icon representing her generation.
The items in this collection include a [Sleeveless Long One-Piece] with a sleek silhouette, a [Crinkled Gauze Front-Opening One-Piece] made from a light crinkled material, and a [Tank Top with Built-in Cups] that can be worn on land and in water while maintaining a beautiful bust line. These items are suitable for a wide range of scenes, from leisure to daily life, and can be enjoyed in various coordinated outfits.
Ms. Risako Miura collaborated on everything from developing the travel-inspired concept to selecting patterns and confirming detailed fittings. The collection focuses on pattern designs that subtly cover areas of concern, and by combining them with outerwear items, it achieves both body-shaping and ease of coordination.
In terms of design, popular textiles from "SPORTIFF" have been adopted in new color schemes. The summery pattern, which combines delicate coral motifs, possesses both a resort-like glamour and an elegance that fits into everyday life.

A tank top with built-in cups from the second "WACOAL Swim Wear x SPORTIFF by Risako Miura" collection.
This is a land-and-water type swimwear top suitable for active scenes.
It uses an under-bust tape that stretches with movement, preventing the bust part from shifting even when moving in the water and keeping the bust shape beautiful. It can be connected to compatible swimwear bottoms with a snap-fit button, making it comfortable and less likely to ride up during wear.
The slightly thicker shoulder straps and straight armhole cutting make any unwanted side bulge less noticeable, and the design allows it to be worn like outerwear. It features a summery pattern with delicate coral motifs, combining functionality and glamour in one piece.
● Ms. Risako Miura's Favorite Points
This light-wearing swim top can be worn both in and out of the water.
I love that the slightly thicker shoulder straps and straight armhole cutting make side bulge less noticeable. It's designed to be worn like outerwear, so it's easy to use outside of swimming scenes.

【Comment from Ms. Risako Miura】
■ For this second collaboration, what points did you focus on?
While many swimwear designs are simple, I focused on creating a design that would make you feel happy when wearing it. Furthermore, to be able to easily wear clothes that match the swimwear, we had SPORTIFF participate in creating the items together.
■ Who would you like to see wear these items?
I would love for active and fashion-loving adult women to wear them.
■ "Wacoal Swim Wear" develops products with a focus on "comfort" and "beautiful body lines." What are your particular preferences for items you use in resort settings?
At resorts, I try to choose items that are comfortable and make my silhouette look beautiful. Among the items in this collection, the [Sleeveless Long One-Piece] and [Crinkled Gauze Front-Opening One-Piece] are essential. Both are so comfortable that once you wear them, you'll want them in different colors, and their timeless designs mean you can love them for a long time.
Also, for travel, they can be rolled up compactly, so it's a great point that you can easily take them on trips where luggage tends to increase.
