In sewing or fashion design, patterns are pieces of paper which are prototypes of clothing parts or sewing products. The pattern is used as an example so that no errors occur while cutting fabric. In addition to using homemade patterns, people can sew at home using ready-made patterns (finished patterns) published by women's magazines.

When making clothes, the pattern is adjusted to the sizes of body shapes and clothing models. For clothing that is sewn according to order, before the pattern is made, certain parts of the wearer's body are measured one by one with a measuring tape. Body parts are measured ranging from the size of the neck circumference, width of the chest, chest length, to waist circumference and length of the back. Before drawing in actual size, the pattern design can also be drawn in small sizes based on the scale in the costume book.

The basic pattern for various types of clothing such as blouses, skirts, dresses, or shirts can be used as examples for sewing, but do not have a model. Skirts from basic patterns, for example, can only be equipped with a zipper on the back, but do not have models, pleats, or wrinkles. When made, the size of the archetype is adjusted to the user's body size or is used by the general body standard size (S, M, L) for men, women, or children.

In essence, the pattern that has been made will be a reference in making clothes so that there are no mistakes in its manufacture, especially during the fabric cutting process.

Actually, even without a pattern, clothing can still be made but sometimes the results obtained are not as expected.
