It's simple. First of all, leggings are pants and stockings are socks. This is the most essential difference. Leggings have a certain thickness and great elasticity, and they are all tight. From the material point of view, there are cotton, denim, cloth and so on. Moreover, stockings are very close-fitting, thinner and lighter than leggings, and some of them are not resistant to hooks, so it is easy to hook holes and loose yarns along the broken places. Generally speaking, stockings are not easy to wrinkle, because they are tight and have the function of modifying the leg shape.
