Most people use a flat sketch template or croquis template when drawing a fashion sketch or fashion technical drawing, particularly when using Illustrator for Fashion Design.
An accurate flat sketch will go into a fashion tech pack, which is a necessity for sampling and manufacturing.
Flat sketches should accurately reflect the overall silhouette, fit, design lines and construction of your design so that a pattern maker has a good idea (just by looking at the sketch) of what you want.
