Designer Donna Karan has famously been a proponent of the sexy exposed shoulder for years, feeling that most women have pretty shoulders to show.
An off-the-shoulder dress instantly shows lots of skin, but not necessarily areas you might be uncomfortable showing like the lower back or cleavage.
The silhouette of the off-the-shoulder dress adds width to the upper half of your body, balancing your lower half. It's a great look for all but those with really wide shoulders.
Accentuate the look with a great necklace, strategically placed brooch or dangling earrings.
