Underwear, also known as pantyhose, tights, five-bone socks or pantyhose, is a garment tightly wrapped from waist to toe. Most pantyhose are specially designed for women. In the United States, pantyhose refers to the combination of shorts and stockings (pantyhose = pantyhose+stockings), and usually no other underwear is worn inside. In Britain, it is called tights. Pants, socks and stockings are generally divided into four types: 1. There are seams in the front and back, not to mention the kind that doesn't distinguish between the front and the back. There are files on both sides, that is, there are two seams on both sides, not to mention, both sides are indistinguishable. This one is very similar to the first one, except that the crotch is added and there is an extra thread, so it is obvious that two lines should be worn at the back. This crotch is carefully designed, with two seams in the front and one seam in the back. The key to distinguish is that you can see the obvious hip design on both sides of a seam. Another difference is that this style generally has a foot anti-slip design, so when you put a seam in front, you will find that the anti-slip bottom of the foot runs all the way to the instep, which is very eye-catching. The correct way to wear jumpsuits: 1. Put one hand into the sock tube, hold the heel, and turn the sock tube to the heel with the other hand. 2. Turn most of the socks upside down and spread them out smoothly, so that your feet can easily reach into the socks. 3. Put your thumb on the inside of the sock, grasp the sock body with four fingers, put your foot into the sock, hold the sock outward with your thumb, pull the sock towards your ankle with your four fingers and put the heel of the sock in the right position. 4. Turn the trouser legs of socks back and pull them up in order, then put them on and fit the Buddha's flat.
