Oh what is there not to love with the Barbie collection. I bought the entire collection and 3 backups of Mothbrown.
My favourite are Don't be shy blush, both beauty powders, Mothbrown (HG e/s), Rocking Chick (HG pink lippie), Sweetness l/g, Style It Up Lippie (HG nude lippie), & Malibu Barbie l/g.
This was the best collection ever made by MAC. If it is rereleased, I will be buying 5 backups of all my faves.
