@TainiFlaremist I will go with basic. I did two sketches: Sketch 1 represents a dress which is tight in the end and presents few folds but significant wrinkles over all the dress ; Sketch 2 represents a dress which has a longer "tail" and causes more folds but in little sizes. For the folds to look balance make sure to have a limit line where the dress will hit the floor and will not pass through to maintain such balance. Hope this helps :D
