One is classified by body type: normal body type, fat body type and thin body type, such as L( 170/92B), that is to say, people with a height of 170CM to 175CM and a chest circumference of 92 or so can choose such clothes. The size of jeans means: W= waist circumference L= inner seam length-middle bone length. Your waist size is two feet four times eighty centimeters =3 1.5 inch, so when you buy jeans, you should buy a waist size of 3 1 inch. Since the length of the inside of your head is about 34 inches (see the following method for measuring the length of the inside), it will be more accurate for you to wear another pair of trousers. So the jeans size you choose should be W3 1L34. Note that most cowboy brands are in inches. In addition, the length of jeans bought is generally dominated by the inner length. Because the waist bottom is high, the length of trousers is affected by the height of waist head, and the length of trousers legs is easy to fit. But if all the inner lengths are measured correctly, the length of trouser legs is suitable for wearing. Note: the inner length refers to the length of the pure trouser leg (measured from the bottom of the crotch to the lower foot). Take pants as an example. Pants are usually knitted in four ways. One is the height-waist cm method, such as 165/68A, which means for people with height 165 and waist circumference of 68cm. 68 centimeters is equal to 2 feet. According to my experience, cotton trousers and formal trousers are generally woven like this. That A refers to the general all-around method, and sometimes there is 165/70B, which is a short and fat special size. Very rare. One is hip circumference method. For example, if you say size 28, that means your hip circumference is 2 feet 8 inches. Ordinary casual pants are woven like this. This one really doesn't look at the waist. There is a certain matching relationship between the waist circumference and hip circumference of their trousers, and a certain hip circumference corresponds to a certain waist circumference. One is the number method, the specific meaning is unknown, but it is generally 36384042, which is the legendary European code. And the alphabet, that is, S, M, L, XL and so on. The size depends on how the brand itself is determined. Generally, m corresponds to 165/66A. Pant size, such as 160/68A, 160 refers to height, 68 represents waist circumference, and A represents body type: normal body type A, obese body type Y, and lean body type. The general conversion algorithm is: 165/68A is equivalent to 27#28 pants and 38# in M and European code. 170/70A is equivalent to 29#30 pants, L and Eurocode 40. Wait, in fact, the size of many brands is not particularly accurate. Generally jeans are more accurate. In addition, the clothes are the same, but it has become a height/bust cm method, such as165/88a; One is the European code method, such as 38, 40, 42, which is the same as pants; One is the S, M, L method. 175/96a= length of trousers is 3 feet 2, waist is 2 feet 9; No.38; 4X； 190/ 104a= height and bust; No.56; 4X；
