MAC Cosmetics has a new collaboration: this time it’s with New York-based fashion label Proenza Schouler. I always like these collaborations. I love the new designs of make up in the style of a brand or celebrity. MAC’s Proenza Schouler Collab is set to launch on April 3rd. The line will include ombre face powders, makeup brushes, eyeliner and lip pencils and nail lacquers as well as lipstick.
