To better understand the relationship between the form underneath and how it influences the drapery on top of it, try this exercise. I have my students do this often, and I still do it from time to time to brush up on my skills.
1 The form beneath. Draw an undraped figure. (A bathing suit will do if a nude model is unavailable.) Give the model a break and have him or her put on a costume with loose-fitting drapery. Have the model assume the same pose as before—this time in costume.
2 Clothing the figure. Now place a sheet of tracing paper over your drawing thats big enough to fully cover it. Draw only the costume on your tracing paper. At times you may find it helpful to lift up the tracing paper to observe the figure underneath and review its relationship to whats on top.
Repeat this exercise several times with a variety of poses. It will become immediately clear how much stronger the drapery studies are in establishing relationships with the underlying structure. While the model is posed with the drapery, try to design the drapery and understand the construction of the various folds.
