Can't exactly call it a dream dress when you are given no information on the dream... Anyway, here is a simple One-Shoulder dress with a modest high low hem (to show off shoes). The top features ruching and a studded strap for a bit of sparkle. The inner-dress is designed to hug but not constrict, while the sheer fabric overlay is suppose to give the dress floatiness.
