In winter, there are thick black silk on the grass. How long has it been? The smell is so strong that the socks are polished.

1, what you don't notice is that black tights are covered with tights and autumn pants, but what you notice is a pair of wool pants with velvet inside. Unlike stockings, the above two kinds of jumpsuits need to wear socks again, but they usually wear boots outside and can't be distinguished. Silk stockings can't survive in our coldest city-minus 10 degrees. If you wear your head, you will be squeezed by the door, and your legs will get cold when you get old.

2. The thick socks you mentioned are also available, which are suitable for the weather around 15 degrees. The thickest is also very thin, so don't try it for health.
