Collaboration items from Ungrid, MERCURYDUO, and AMPHI to be released on Friday, April 24

Women's brands "Ungrid" and "MERCURYDUO," operated by MARK STYLER Co., Ltd. (Headquarters: Shibuya-ku, Tokyo; President and Representative Director: Masanori Akiyama), will each release collaboration items with the innerwear brand "AMPHI," operated by Wacoal Corp. (Headquarters: Kyoto City, Kyoto Prefecture; President and Representative Executive Officer: Keisuke Kawanishi). Sales will begin at 15:00 on Thursday, April 23, 2026, on the official online stores "RUNWAY channel" and "ZOZOTOWN," as well as at retail stores nationwide and e-commerce sites such as the Wacoal Web Store.

Additionally, advance reservations will be accepted starting at 13:00 on Thursday, March 26, on the official online store "RUNWAY channel."

This collaboration was realized because Ungrid and MERCURYDUO, despite their different styles, shared a desire with their common partner, AMPHI, for customers to "enjoy innerwear more freely as fashion."

In developing these products, the comfort and innerwear design expertise that AMPHI has always valued were fused with the unique worldview and design aesthetics of each brand.

The result is a collection of cup-equipped items that can be enjoyed as fashion, with lineups that leverage the unique characteristics of each brand.

Both Ungrid and MERCURYDUO items share a design focus on comfort and beautiful silhouettes.

The bra tops feature sewn-in peanut-shaped pads. The pads are thicker in the center to create a three-dimensional bust silhouette just by wearing them. The integrated, one-piece pad prevents the bust from spreading, providing a clean look around the underarms. The under-band is hem-finished without elastic to reduce back bulges, ensuring a comfortable fit.

A back-open T-shirt with built-in cups made from soft ribbed material. Since it includes cups, it can be worn on its own, solving the difficulty of choosing undergarments for back-open designs. The neck design, which focuses on color coordination, is another highlight. With its cropped length, it is an item that can be balanced well with various bottoms.

The highly elastic material fits the body, creating a compact and clean impression. It is useful as an inner layer for various summer items, such as tops with large open backs, items with low necklines, or sheer clothing.

A three-dimensional bandeau top featuring delicate tiered lace. Despite being an inner layer, it has a presence worthy of being the main piece, glamorizing the neckline. The camisole straps have adjusters for length customization. Being a cropped length, it is easy to use as an inner layer for short tops and broadens the range of layered styles.

A dress that can be worn as a single piece, featuring a docked bra top with cups. The subtle side cut-out design provides a healthy peek of skin. The back is accented with a matching ribbon, ensuring the style is impeccable even from the back. It is a piece that accompanies women's daily lives, allowing them to easily enjoy cuteness.

Receive a collaboration mirror with purchases of 7,700 yen (tax included) or more, including eligible items.
