Calling all fans of The Simpsons: If you haven’t already secured your tickets to San Diego Comic-Con, make plans to be in the area on July 26! For one day only, MAC’s Marge Simpson makeup collection will be available for purchase before the official nationwide launch.

We’re already fans of the bold hues and fun packaging in the sneak peek above, and luckily, so is Marge herself. “I must say that Lisa’s Spikes works well with my skin tone,” the blue-haired beauty says of the yellow gloss (above, right). “Of course, Beehive Blue (above, at top) complements my hair perfectly.” No need to enlist the services of Craiglist or eBay for a Comic-Con badge—the collection can be found at the MAC Cosmetics Gaslamp outpost on 234 Fifth Avenue, so be sure to mark your calendar for July 26, and head over early before stock runs out. Not in the San Diego area? Not a problem! You’ll be able to shop the full range online at maccosmetics.com on Aug. 28 and at your nearest MAC counter starting Sept. 4.
