Deschanel recently rediscovered the message and took to her Twitter.com page to share it with fans, insisting she's "proud of my feminist teen self".
Deschanel's letter to Vogue states, "Why would you want to limit the spectrum of beauty to an 'ideal' when you, as a popular women's magazine, have the opportunity to expand it? I don't think any woman should have to feel as if she needs to shove herself into an 'ideal' to be beautiful.
"Beauty should be something that is celebrated and something that is enjoyable, not something that people should feel uncomfortable about achieving. Most of the women, and certainly most of the adolescent girls, in the United States do not feel completely secure with themselves, especially with their appearance; is insecurity something you want to advocate? As American women, we don't need discouragement, but inspiration."
The actress then tweeted: "No hard feelings Vogue magazine, love your mag! I was a feisty 17."
