In sewing and fashion design, a pattern is an original garment from which other garments of a similar style are copied, or the paper or cardboard templates from which the parts of a garment are traced onto fabric before cutting out and assembling (sometimes called paper patterns).
Patternmaking, pattern making or pattern cutting is the art of designing patterns.
A custom-fitted basic pattern from which patterns for many different styles can be created is called a sloper or block.
Home sewing patterns are graded, that is, redrawn to fit larger and smaller sizes than the original design. Ebenezer Butterick invented the commercially produced graded home sewing pattern in 1863 (based on grading systems used by Victorian tailors), originally selling hand-drawn patterns for men's and boys' clothing. In 1866, Butterick added patterns for women's clothing, which remains the heart of the home sewing pattern market today.
