The cups feature the unique soft stretch cups of the "Koi Suru Bra," perfectly fitting the body's movements and creating a natural silhouette. The holes at the bottom of the cups provide good breathability. The back has been updated to a flat design using fabric made from recycled nylon yarn, making it less likely to show through outerwear. The cup lining is a cotton blend. Lightweight and breathable fiberfill pads provide a natural volume boost (available in select sizes: A-B cups, C65-75, D65-70). The cups are designed to gather the bust, with stretch control on only a portion of the sides (available in select sizes: B80, C65-85, D65-85, E65-80). The NEW "Angel Wire(R)" is less likely to dig into the skin. The straps are "Kata Raku Straps(R)," which are made of highly elastic fabric and tape that extends from the back, fitting the shoulders and stretching well. The strap fasteners use a special triangular shape called "Delta Magic(R)," making them less likely to slip off the shoulders. The shoulder straps have adjusters for length adjustment (non-replaceable). Sizes C cup and above have side bones. ■ Hooks & Eyes: 1 row, 3 columns: A(70), B(65) 2 rows, 3 columns: A(75), B(70/75/80), C cup, D(65/70/75/80), E cup 3 rows, 3 columns: D(85/90) ■ Bra Size Availability: A70 A75 B65 B70 B75 B80 C65 C70 C75 C80 C85 D65 D70 D75 D80 D85 D90 E65 E70 E75 E80 ※ Size availability varies by color. ※ Sizes C cup and above have side bones. ■ Padding: Available in select sizes ※ Sizes with padding: A-B cups, C(65/70/75), D(65/70) ■ Materials: Nylon, polyurethane, and others ※ For patterned products, the pattern may appear differently from the image due to the cutting process.
