Roseanna's River Moss dress feels modern and vintage all at once.  The River Moss dress has a plunging neckline that can be fastened at the top to create a round neck.  A gathered drape at the hips and a high slit creates a stunning silhouette that lends vintage vibes.  It is worked on the reverse of the satin to create a matte look to the fabric that feels modern and unconventional.  100% acetate.  Dry cleaning recommended.  36=small 38=medium 40=large. This style runs small, particularly through the hips.  Margot is 5'4" and is wearing the 36.
