Shape is held or destroyed according to the settings you have in the following :
Bend Resistance
Shear Resistance
Stretch Resistance
Cloth Density
Unfortunately the relationship between these settings are not really explained, which leads to epic frustration!
Bend Resistance controls how much each vertice tries to keep its angular relationship to the vertice around it. higher numbers will help keep shape of folds etc.
Shear Resistance controls how much each vertice tries to keep its angular relationship between adjacent vertice according to the normal direction of the polygons attached to the vertice. increasing this number will help keep polygons from becoming to skewed.
Stretch Resistance controls how much each vertice tries to keep its distance from all vertice attached to the same polygon. Increasing this will help keep polygons from bunching together and collapsing.
Cloth Density is the amount of weight added to each vertice to allow gravitational calculations. Higher weights will require higher resistances to stop the material acting unrealisticly.
The most likely cause of your issue is that cloth density is high enough that it is completely overcoming bend and shear resistance, instead being controlled mostly by just stretch resistance. As the cloth stretchs it will flatten out areas of cloth to ensure that the amount a vertice stretches is the least amount possible by "bending" and "shearing" the vertice before stretching it.
That probably makes no sense at all!
