KATIE EARY
Her designs are really colorful and animals:
Then I suggest you to google Katie Eary to find more designs of her and to be more inspired!
Dress your doll with this theme and take a screenshot of it. (you really need to take a screenshot for your application, I won't look at your dolls manually)
Then just post a comment with your stardoll username and the link to the screenshot of your outfit. (you can use tinypic, imgur...)
Good luck!
