The "firmness makeup sheet" on the cup side lifts the bust from below and gathers it inward, creating a full, firm décolletage. 3D soft pads firmly push up the bust from below. The side bones of the "firmness makeup sheet" are only included for D-F cups. The cup material uses "Angel Cushion Light," which has excellent shape retention. It provides a soft and light feel while creating a beautiful bust line. The pad pocket uses 100% cotton material. The back is a flat design using microfiber, making it less likely to show through outerwear. The "NEW Angel Wire" is used, which has a thin, flat wire at the front center and is curved outward. It is less likely to dig into the skin and cause pain. The shoulder straps have adjusters, allowing for length adjustment.
