When we lose weight, we always wear an abdominal belt inside to tighten our stomachs and reduce our food intake. Eating less will make you feel full. At the same time, it plays a role in restraining pantyhose.
This kind of abdominal belt is found in many places where underwear is sold.
However, the coat should be opaque and slightly thick to avoid the exposure of the abdominal belt, and the imprint must not be seen by people.
Have fun. . . . .
