What's the best online site to buy a woman's designer dress?

The good news is that there are are a number of ways to wear a couture gown and still be green.  If you are looking for a specific designer, you can buy a once worn gown from designers like Oleg Cassini, Amalia Carrara and Vera Wang at the Wedding Dress Market and Save the Dress.  If you live in New York, try The Bridal Garden (54 W. 21st st) which raises money for the non-profit Sheltering Arms Children's Services. If you want to wear a new gown, Brides magazine ran a Something Pink issue featuring designer gowns whose sales proceeds go to support breast cancer.
