One of the latest collections to come out is the MAC Casual Colour Collection for Summer 2012. It's available on line right now, and should hit stores on June 7th. This is how the MAC Cosmetics website describes the collection:
"This is weekend chic, M.A.C. style. Mineralize Skinfinish, Studio Fix Mascara, Prep + Prime Highlighter, and new all-in-one Lip and Cheek Colour Pots. Effortless and easy, this barely there formula feels like wearing nothing at all."
