Here's a tip for searching for stuff online...for things like dresses. Enter into your favorite search engine (Google) site:
For example, when I type a name of a dress that I'm looking for...I get a lot of results from partypop.com which is one of the crappiest forum sites ever. There's no way to notify posters privately and to get contact info - you have to post it up where any one (hello spam) can see it.
So enter into the search box something like:
Allure Dress Blah -partypop.com (to exclude sites)
site:craigslist.org Jim Hjelm blabblah dress (to specify sites)
So what did I get from Craigslist? I picked up one of these babies...barely used and for less than half the price! Make room for little sister, brother Yudu!
