Fafi's MAC collaboration hits stores tomorrow. The famed grafitti artist's collection is sure to be another Special Edition sell out for MAC. We loved the Barbie lipsticks, and the Alexander McQueen eyeliners, and with Heatherette next in line, we're curious: Do you buy collector beauty? We can maybe see the appeal if you're a big Fafi fan, or a makeup artist, but our big fear is falling in love with a particular limited edition shade, then poof! It's gone...only to be found for triple the price on eBay. Do you simply use the empty compacts to accessorize your vanity? Or will you skip the eyeshadows and just purchase the adorable "Fafinette" doll as a keepsake? -- JAZZI McGILBERT ps: Fafi herself will be at Henri Bendel tomorrow from 4-6!
