Taking the material with a width of 2.7 as an example, the calculation method is as follows:

(1) the materials for men's tops are: 3 clothes and 0.3 feet.

If the length of a garment is 2.3 feet, the amount of material needed is 2.3 x 3 + 0.3 = 7.2 (ruler).

(2) the material for a woman's coat is: 3 clothes.

If the length of a garment is 1.9 feet, the amount of material needed is 1.9 x 3 = 5.7 (ruler).

(3) male trousers are made of 2 trousers and 0.3 feet.

If you make two pairs of trousers, the waist of the trousers can be cut within 2.3 feet, the material is 3 pants, and the border is 0.3 feet.

(4) women's trousers are the same as men's trousers.

If you make two pairs of trousers, the waist of the trousers is within 2.3 feet, the hips are less than 3.2 feet, and the trouser legs are not more than 0.7 feet, they can also be used for cutting. The material is 3 trousers and the edge is 0.6 feet.

When buying double cloth (4.3 feet wide), the method of calculating the material is:

(1) the male clothing is: 1 coat length, 1 sleeves, plus 0.3 feet, and then 3.

If the length of a garment is 2.2 feet and the length of the sleeves is 1.8 feet, the amount of material needed is (2.2 + 1.8 + 0.3) 3 3 = 1.43 (meters).

(2) to make trousers, only one trousers can be used.

(3) make an overcoat, use 2 coats and 0.3 feet.
