This long plus-size prom dress in navy jersey is beautiful as well as interesting. Barely masking a contrasting white lining, a navy blue bodice fashioned from floral-patterned lace makes this plus formal evening dress unique. Adding to the appeal, solid scalloped lace trim outlines the v-neck bodice and travels down the front in an eye-catching vertical line. This plus-size prom dress defines the figure with a band surrounding the natural waistline and a curve-hugging floor-length skirt, making every inch of this design wonderful.
