This collaboration was realized from the desire of "Ungrid" and "MERCURYDUO", which have different tastes, to enjoy innerwear more freely as fashion, together with their common partner "AMPHI", from their respective perspectives.
In product development, the comfort and know-how of innerwear design that "AMPHI" has valued were fused with the worldview and design sensibility of each brand.
We have completed cup-equipped items that can be enjoyed as fashion.
We will offer a lineup that leverages the unique characteristics of each brand.
Product Introduction
Both "Ungrid" and "MERCURYDUO" items feature specifications that prioritize comfort and a beautiful silhouette.
A bra top with a sewn-in peanut-shaped pad. The pad, which is thicker in the center, creates a three-dimensional bust silhouette simply by wearing it.
The integrated pad on both sides prevents the bust from spreading outwards and gives a neat impression around the sides. The underbust is a hem specification without elastic, reducing the appearance of back lines and ensuring a comfortable fit.
