A refers to normal body shape (there are four body shapes, Y stands for thin, A stands for normal, B stands for fat, and C stands for obesity), and the general models XXS and C are recommended. It is recommended to choose a suitable corset to keep comfortable. For example, the corset of Adidas training series has system size.
