This is a gorgeous off the shoulder party dress Perfect for any occasion the main is a 100% viscos the trim is a 100% cotton. It's a size 18/20 but in my opinion it runs kind of big but you can adjust with the draw strings in the middle of the dress to either make it tighter or looser fitting Slightly higher front low back to give you that flowy effect. This dress was purchased online at Avenue it's one of their new rollouts by aveology .
