High-quality body-shaping underwear (that is, body-shaping underwear) is based on the principle of fat fluidity, which gradually restores the lost, displaced and drooping fat to the correct position and locks it vertically, and finally makes people still have towering breasts, slender waist and round upturned buttocks when they take it off. Different from the previous abdominal girdle and waist seal, it has changed the previous practice of treating headache and foot pain, not only by adjusting the local shape, but also by transferring excess fat from various parts of the body (such as breast, stomach, abdomen, waist, back, armpit and other parts) to appropriate positions, so as to make the body concave and convex, thus achieving the effect of slimming and beautifying. Because 95% women in China lack physical knowledge and wear sponge bras and unscientific underwear for a long time, the fat originally belonging to the chest is lost to the armpits, stomach and back. The main purpose of adjustable underwear is to transfer the fat from the back, shoulders and armpits to the front chest, so that the chest shape is round and full. Through the underwear design of the back and waist, the figure is tall and straight, avoiding chest, hunchback and gastroptosis. Body-shaping clothes tighten the fat on the buttocks, and combine with waist clips to guide the fat on the waist, abdomen and thighs to transfer to the buttocks, thus shaping a beautiful hip shape. High-quality body-shaping underwear has good elasticity, and can cultivate one's self, lift one's hips, flatten one's abdomen and hold out one's chest. The general principle is to keep fat in the best position. For example, push the fat flowing to the stomach back to the cup to increase the bust, and stir up the excess fat from the abdomen down to the buttocks to create a flat and tight abdomen; Lift the hip fat up to make it look round and elastic. Real high-quality body-shaping underwear adopts three-dimensional cutting method. Through three-dimensional cutting, the chest can not only contain the breast three-dimensionally, but also abandon the steel bracket, and the supporting force is not reduced.
High-quality adjustable underwear will consider using memory alloy technology to prolong the wearing time of adjusted underwear as much as possible. When it is worn for a period of time and its body shape becomes better, it will automatically "design" the most suitable shape and size after the change. ROICA (polyurethane fiber) and polyurethane (polyurethane) combined space fiber contain negative ions like the body, which can rub free fat. They can also maintain excellent air permeability and heat dissipation, keep human metabolism normal in warm winter and cool in summer, and can be worn on the body for a long time without any adverse effects. The adjustable underwear in the market generally uses space fibers made of Rocca and spandex, but the spandex content in space fibers is generally around 10%, and the spandex content in space fibers of good adjustable underwear can reach 45%.
