I just got back from a Barbie event too!!
They had a DJ, bartender, and it was catered... There were adorable sugar cookies with Barbie's silhouette on them!! I'm not sure what the alcoholic drink was, but it tasted great! It was pink, had cherries, in a martini glass, and instead of having salt on the rim, it had pink sugar sprinkles!
Besides the drink, there were SO many MA's, all wearing Barbie Loves MAC shirts, some pink shirts, and some black shirts.
I only bought an eye shadow (Springtime Skipper) and lipglass (Malibu Barbie) because my bf is getting me the Barbie, and more makeup on the 13th as soon as it opens. We're skipping our classes, LOL! I don't think my undergrad professors will excuse me, but for MAC, I don't really care!
PLUS I got postcards!!! I got the black/pink one and the round compact one.
