Style diva Katy Perry is doing her bit to raise funds for the Red Cross by auctioning off one of her lovely dresses on Ebay.

The dress, designed by Todd Thomas, has a heart-shaped bodice encrusted with red Swarovski crystals and skirt in pink tulle which resembles cotton-candy/candyfloss.

This dress will be worn by her on her California Dreams World Tour and Katy will personally hand over the dress to you backstage at her November 21st concert at the Oracle Arena in Oakland, California. If you win the bid, you and a guest will get VIP seats to watch her show.

All proceeds from the winning bid will support American Red Cross Disaster Relief, helping people affected by disasters such as the 2011 spring storms.
