Revered artists like Andrew Loomis explicitly state why is absolutely necessary to draw the naked body in order to understand the clothed figure. The same way Loomis also states it is necessary some degree of skeletal anatomy knowledge to draw the naked figure.
If you have the naked figure correctly, then you have the base for the "rules of their own you have to account for"
He and other artists also go into drapery folds with simple forms. You take those rules and apply them to the more organic forms of the nake figure and you have a clothed person
