Technical drawing for fashion must be true to sewing technology.
All aspects and details of sewing have to be accurately visualized (seams, top stitching, trimming, darts, gores, buttonholes).
Fashion technical drawing must be informative with clear depiction of all seams and stitched relevant to illustrated garment. As a rule, hem lines and details (such as pockets) are top stitched in all standard items of clothing.It is essential that all fastenings in the garment must be accurately depicted as well. According to leading fashion consultant agency Smith & Pye " a successful flat drawing ... displays the appropriate details for manufacture i.e. seams and fastenings."[i]
