To improve the quality and overall look of the dress you can perform a polygon smooth. Polygon smoothing will increase the number of polygons in your nCloth mesh to give it a smoother overall appearance.

To smooth the dress

1. Select the dress and in the Polygons menu set select Mesh > Smooth.
2. Return to the nDynamics menu set.
3. Select nCache > Create New Cache.

   Maya automatically plays back the nCloth simulation and saves it to disk.

4. Playback the scene.

   The dress in the final animation is smoothed giving it a much silkier appearance.
