I am trying to pick out colors for my wedding that will be in June of 2012.  I will be ordering dresses from David's Bridal for my bridesmaids.  From there, I can't decide if I want to get dresses in the following colors: (they are all some shade of aqua/blue) Oasis, Cornflower, or Pool.  Here is the link you can go to to see the dress style and you can click on the different colors as well: http://www.davidsbridal.com/Product_Cotton-Sateen-Strapless-with-Ruching-and-Pockets-83312_Bridal-Party-Bridesmaids-All-Bridesmaid-Dresses

Any suggestion on which color of dress I should go for?  Originally, I wanted orange dresses; however, I cannot find a shade of orange from David's Bridal that I like.  So, I'm wondering what colors I can use for flowers with any of those colors listed above.  I was thinking yellow would for sure go along with any of those colors.  But I'm wondering if orange would go with those colors?  Any suggestions on flower colors for the dress colors I've listed above?  It's so hard to envision everything!

Thanks for your help!
