The stick figure look owes more to fashion design than it does to Clamp. In fashion design all the figures are draw as these inhumanly thin caricatures so that its easier to add and remove the elements of the clothing (which is the point). Unfortuneatly the purely practical design aesthetic has become an the ideal design aesthetic. Supergals, for example, follows this design aesthetic religious because the series is as much about the fashion as it is the characters.
