I took birthday girl to the store to choose the barbie. I new we needed a "slimmer" hipped barbie. When you start shopping for the barbie you will see what I mean.
For the cake: I used a metal bowl and then shaped it to fit her body.
You just dig and hole out and push the barbie right down in the cake.
The frosting was just made with different pinks and orange jell food coloring until we got the right color. The cake actually served about 10 people. It was bigger than it looks.
