The outfits on the third season of “American Horror Story” all had one thing in common: black. And it looks like Emma Roberts, who played Madison Montgomery, decided to carry out that trend into her everyday life.

At Coachella, Roberts donned a simple black slip dress and accessorized it with a flannel shirt wrapped around her waist, black converse, a gold necklace and sunglasses, demonstrating the essence of the very versatile little back dress (“LBD”).

Whether you’re going to a music festival, shopping with friends or going to a nice dinner, a simple black dress is perfect for any event. Dress it up with some heels, or dress it down with sandals or flats. A baby doll or slip black dress can be effortlessly transformed from day to night. 

Plus, since black is slimming and is an absence of color, a LBD goes with any and all skin colors and body shapes.
