1, thick texture, stiffening effect: woolen fabric is composed of thicker fibers, which makes the fabric itself thicker and has a certain stiffening effect. This feature makes the silhouette of clothes wearing woolen fabric more obvious and can effectively modify the figure curve. Suit fabrics are usually thin and soft, which can't achieve the same three-dimensional effect.

2. Uncomfortable design: The design of woolen fabrics tends to be loose or slightly fluffy, and will not cling to the body. It can cover some problem areas of the body, such as the bulge of the abdomen or buttocks, and make the whole body look more slender. Suit fabrics are often tailored to fit the body curve, which will highlight some shortcomings of the body.
