In order:
1. Ball shaped outies, think Julia Voth, Toni Braxton, Alicia Fox, and Annalynne McCord.
2. Complex outies and inbetweenies, think Emily Ratajkowski and Kendall Jenner (the more lines and details, the better).
3. Very large and very deep innie, think Ariel Winter or Maria Kanellis (no other type of innies will due, in other words, must be polar opposite of Stacy Keibler).
