Audrina Patridge is just one of several celebrities participating in an auction to benefit the charity Chrysalis. Patridge wore a dress from Found By, a West Hollywood boutique. Found By sells "unique vintage finds," and you can shop them online.
The dress worn by Audrina Patridge is a vintage red snake print mini with a 21" waist.
The original plan was that Audrina Patridge, along with other celebrities, would wear one of the boutique's vintage dresses to the grand opening of Found By. Those dresses would then be auctioned off to benefit charity. Patridge was unable to attend the event, but still participated by wearing the outfit to another event.
