Accept your body's limitations. Christina Ricci reportedly asked the trainer with whom she worked before her body-baring scenes in "Black Snake Moan" to help her get "Jessica Biel's butt." Ricci's trainer explained to her that her petite behind would never be as big as Biel's, so Christina accepted his advice and worked out to achieve a magnificent derrière that looks great on her tiny frame.
Eat whatever you want, but eat it in modest portions. Christina Ricci has explained to interviewers that she eats all the foods she likes, including fattening stuff, but she eats small portions and works out to keep from packing on the pounds.
Get comfortable in your skin. To prepare for her role as Rae in "Black Snake Moan," Christina Ricci, as a self-described "prude," had to get used to being mostly naked in front of an entire film crew as well as one of her idols, Samuel L. Jackson. Ricci said she stayed in Rae's character and walked around in very little clothing so she could grow accustomed to that state when it was time to film her scenes.
Dress for your body type. Christina Ricci, who is tiny, wears shorter, curve-hugging clothes to keep from overwhelming her petite figure. Dolce & Gabbana, Gucci and Yves St. Laurent have all adorned Ricci's small frame.
Overcome low self-esteem. Christina Ricci has admitted to suffering from anorexia in her teens. Like her character in "Penelope," Ricci overcame her insecurities and now works out and eats a balanced diet to keep her svelte body looking fabulous.
