Technical drawing must be true to patternmaking:
- For fitted silhouettes darts and/or gores must be depicted (unless it is stretchy fabric).Otherwise, it is not clear how fitting was achieved.(examples)
- Flared hem can be depicted in two different ways for the reason that there are two ways how extra fabric in a flared hem could be illustrated:
- a flared hem could be illustrated as flattened (as if laying on a desk)
- a flared hem could be illustrated as hanging (as if hanging on a hanger). To show flared hem hanging on a hanger always depict flare lines towards the waist line, not towards the side lines.
- To show gathers always start gathers from a seam
- For full, volumetric silhouettes flaring, gathering, or drapery must be depicted. Otherwise it is not clear how volume of a garment was achieved.
- Use bigger ease for outer garment and smaller ease for underwear.
- Front neckline, as a rule, is deeper than back neckline (exceptions are designs with deeper neck line (décolleté) on the back).
- The angle between hemline and side seam must always be 90 degrees right angle.(examples)
- The angle between central line of sleeve and hem must always be straight 90 degrees right angle.
