(Cover) - EN Star Style - Tyra Banks, Elle Macpherson and Brooke Shields are among stars donating dresses to charity.

Model Elettra Wiedemann has teamed her organisation OneFrickinDay with online auction site Charitybuzz for the initiative, which is called Model Behaviour. OneFrickinDay aims to raise money for good causes by encouraging more people to give a small amount of time or money, which is why the stars have been asked to give up one of their favourite frocks.

We have asked about 30 top models, including Tyra Banks, Eva Herzigova, Brooke Shields, Elle Macpherson and Christy Turlington to donate one frickin dress they have worn on the red carpet, she told People. These gorgeous dresses will be auctioned off on Charitybuzz and the money will go towards buying solar panels for clinics that currently have zero access or very limited access to electricity in Rwanda and Haiti.

Elettra hopes at least $100,000 will be raised by the initiative. The dresses can be bid on by visiting the Charitybuzz website.

Selena Gomez previously used the auction site to sell off a dress, with proceeds going to global collective UNICEF, for which she is an ambassador. (C) Cover Media
