1, check the materials. There are many kinds of materials for velvet leggings, such as cotton, polyester, nylon-proof and nylon masks. Different materials have different prices. Some leggings are of low quality, as long as 10, 15 yuan. Many of these leggings are made of nylon, which is easy to fluff. At present, the materials of nylon masks and smooth pants in the industry are better. Material is also an important factor to determine the elasticity of leggings. Good material and high density, so leggings are not easy to pilling and will be more elastic.

2. Look at the details. Looking at the route details and equipment, many velvet leggings are just "front and back", that is, the front and back are exactly the same, so these leggings will be too tight to wear.

3, gently brushed. Many velvet leggings in autumn and winter will be velvet. Gently pull the fluff inside the leggings with your hands, and it will fall off under very light force. This kind of leggings will fall off when you wear them, when you take them off and when you wash them.
