Filed: 1995-02-08
Abstract: PURPOSE: To obtain the subject underwear capable of putting on and off in a simple manner, easily wearable like an underwear and enabling the control of the waist line by just wearing it. CONSTITUTION: A belt-shaped material covering the upper abdominal part is produced by using a soft underwear cloth having larger elasticity in longitudinal direction than in lateral direction or a soft underwear cloth having little stretchability. The both ends of the belt-shaped material are attached with a pair of fasteners or Magic Fastener(R) in lateral direction, which are to be adhered to each other, to obtain the objective underwear. The underwear is put on the upper abdominal in a state that the both ends are closed at the front side of the body. The elasticity or the shape of the underwear cloth is adjusted to fit naturally on the upper abdominal and the cloth gives light pressure in the range which can keep the feeling of fitting. The wearing of the underwear for a long time works to remove surplus fat to control the waist line.
