When choosing the right pair of undies to wear under a tight dress, it has to be made out of a thin material and practically invisible, which isnt always the easiest to come by

Instead, opt for interesting details like draping, cutouts, boning or a touch of lace or beaded appliqus for an eye-catching gown that is not over the top
