When it comes to cutouts, placement is critical. The cutout needs to add "value" in some way, maybe showing a little skin to help elevate a dress (or other item of clothing) into a sexier stratosphere.
The cutout on this structural green dress from Halston Heritage is very intentional. While keeping with the overall architectural design of the dress, the asymmetrical cutout allows a little cleavage to show through. Combined with the color, it helps this seemingly normal fit and flare dress really stand out. (The color is even more bold and beautiful in person.)

It's hard to tell form the photo, but the buds on the shoes have a green center that perfectly matches the green of the dress!
