Do not spare yourself in drawing from the living model, draped as well
as undraped; in fact, draw drapery continually, for remember that the
beauty of your design must largely depend on the design of the drapery.
What you should aim at is to get so familiar with all this that you can
at last make your design with ease and something like certainty, without
drawing from models in the first draught, though you should make studies
from nature afterwards.
_William Morris._
