First barbie, first pic is bugging me.. I've run into this one a few times lately and I cannot find a perfect ID for it. It is almost exactly 1993 Glitter Hair Barbie (same head mold, makeup, bangs, hair length, etc) but the earrings are wrong. Glitter Hair Barbie should have palm tree earrings.
I'm going to put a temporary ID on that one..
Now, second picture, first doll someone Id'd earlier as wearing a certain Generation Girl's outfit. But I found a flickr user with that exact doll wearing those exact clothes, so I'm going to assume it was just a reissue on the pants for the generation girl.
