The material is made of a slightly raised fabric called peach skin, which reduces the discomfort of the fabric clinging to the skin. The seams that touch the skin are on the outside, with consideration given to the feel of the material on the skin. The undergarments are made of non-elastic front and back, so there is no itching or tightness, making it stress-free. The shoulder straps are also made of a wide, slightly raised fabric, which gives a sense of security when worn.
