Where can I find a prom dress similar to this? Or the flowy style of it?

That dress is gorgeous! Let's see what I can find...

Maybe Jovani has something you'll like. (They have a tab on their site where you can look up retailers close to you as well.) Here are some from their site...

Here's one: http://www.jovani.com/index.php?option=com_product...

If you end up wanting another color, here is one with a style much like the picture you showed (and the back of this dress is absolutely gorgeous as well): http://www.jovani.com/index.php?option=com_product...

Another one with a lot of color: http://www.jovani.com/index.php?option=com_product...

Here's one in solid pink: http://www.jovani.com/index.php?option=com_product...

Macy*s has one that's a bit different (and green) but it's really affordable (and I love green formal gowns, they're really unique, I wish I could've found one that I loved when I was in high school!): http://www1.macys.com/catalog/product/index.ognc?I...

Other reliable stores to try include Bloomingdale's, Von Maur, Dillard's, DEB, ASOS, and Younkers.

I hope I helped! :)

PS My friend rented her dress and something did happen to it - someone else spilled something on her, so, it's a good idea but you'd have to be really careful or willing to pay if you aren't, but at that point - wouldn't you rather just own the dress? Just my opinion though. Some people do it and it works out really well. :)

Why buy it when you can rent it? Check out Rent the Runway.

This fantabulous company was started by two women from Harvard who wanted to make couture style available (and affordable) for everyone. The only drawback is that if anything happens to the dress you will be responsible for the full cost (watch out for grape juice)! Otherwise, it works like Netflix--you rent couture for a few days and then return the dress in their pre-paid envelope. Brilliant!
