Create an image featuring a figure with medium-length wavy hair, wearing a flowy lavender dress with a unique asymmetrical neckline. The figure should be posed sitting, with one leg crossed over the other. Instead of a shiny embellishment on the dress, add delicate lace trim along the edges. Change the background to a soft pastel gradient, and make the lighting warm and inviting. Ensure there are no brand elements visible in the design.
