Our wacoal ワコール Crossing the boundaries of lingerie and clothing: Cup-in Wear A back-open T-shirt with cups that fulfills the roles of both a top and lingerie in a single piece. Taking advantage of the built-in cups, it features a design with a large open back, greatly expanding the range of your daily styling options. By using molded cups that are integrated left and right, a beautiful bust silhouette is achieved. The cup portion uses a free-cutting material without underbust elastic, reducing the appearance of back bulges. 【Size Details】 M: Body length 58.5cm, Sleeve length 57.0cm, Shoulder width 31.0cm, Back drop 22.0cm I purchased the wrong size, so it's new and unused with tags.
