We all knew it would happen sooner or later: Summer is coming to an end. But instead of piling on graphic prints and bright colors in a desperate attempt to hold onto the season, celebs are taking the more mature route and bidding it adieu with all-black ensembles.

Head-to-toe black can look equal parts chic (Audrey Hepburn in "Funny Face"), mysterious (Catwoman) and fashion-forward (the entire coven on "American Horror Story"). The key is mixing textures, playing with shapes and knowing how to style the monochromatic look -- three things these celebrities have down pat.

While most of her blue carpet peers wore summery crop tops, Selena Gomez wore a sophisticated Saint Laurent suit to the 2014 Teen Choice Awards in Los Angeles.

The actress matched her raven hair to a black Lanvin dress and black Saint Laurent pumps when she dressed her baby bump for a special screening of "Guardians of the Galaxy" in New York City.

Whitney Port proved crop tops can make it through fall. She paired hers with an oversized blazer, high-waisted pants and gladiator-inspired sandals at the Gilt + Cambridge Satchel Company breakfast in New York City.

Julianne Hough's racer front top, peplum and shorts combo gave her all-black look a summery feel for the premiere of "Let's Be Cops" in Los Angeles.
