If nightgowns call to mind high-collared granny gowns, think again. From vintage Hollywood glamour to modern gowns that flaunt it all, nightgowns are the most versatile of sexy sleepwear. When you're going for a seductive look, there are lots of options. Long satin nightgowns with low necklines and fitted bodices can be pure glam. To show off those legs, try a short sexy chemise style nightgown or a long gown with a high slit. Sexy nightgowns are also available in sheer fabrics, both loosely flowing or body-hugging with a touch of stretch.
