In fashion illustration you must retain the basic proportions of the human form from head to crotch, only add extra length to the legs to give dramatic stylised effect and give your designs more dynamic appeal.
In drawing your figure should be drawn long and slim with squared off shoulders and very unrealistically elongated legs. It will look extremely out of proportion, as the legs tend to be exaggeratedly long. The waist must be drawn very slender.
In drawing your figure, remember that the waist is one third down from the top of the figure. It is most important to show this important aspect of the figure, which will add to the elegance of your croquis.
