Wacoal underwear is mainly comfortable, but also has a good gathering and lifting effect, and the underwire will not be pressed on the breast, suitable for women of all ages and the pursuit of simple and comfortable underwear. The charm 3D series and the UP UP series are Wacoal's star products. The Charm 3D series adopts a "three-dimensional rotary structure" version, and the cups and sides of the earthen platform are made of non-elastic fabrics to form a linkage side thrust force. The use of elastic fabric at the lower slope of the cups strengthens the tension of the underwire, turning the cups inward, so that the breasts are more concentrated and lifted, creating a three-dimensional and rounded visual effect. The cup surface of the UP UP series is made of European baroque lace, and the edge of the cup is designed with openwork mesh, giving it a feminine and elegant feeling. The inside of the cup is a non-underwired version, which reduces the pressure from the underwire. The lower part of the cup is thickened in a large area, and the upper part is thickened in a small area, which is double-lifted to effectively shape the three-dimensional breast shape. The price of the charm 3D series and the UP UP series is about 300 yuan, and it is also a good choice for underwear at the same price.
