A method for positioning panels is for a garment in a digital clothing. The method comprises steps of: providing two orthogonal grain lines comprising horizontal and vertical axes; providing a pattern making window with a horizontal line and a vertical line; providing a panel positioning frame imbedded in a panel for encoding a relative position of the panel with respect to a human body; positioning the panel on a corresponding offset plane and adjusting an amount of offset; providing panel positioning tips to the panel for encoding a body-related position of the panel and storing the panel positioning tips in a panel data; grouping a plurality of related panels and creating group landmark lines; and creating the garment by positioning the panels at proper locations.
